This diode has its anode connected to the output and its cathode to the input. The internal diode is normally reverse biased, but will conduct if the output is forced above the input by more than a VBE (approximately 0.6V). Current will then flow from VOUT to VIN. For safe operation, the maximum current in this diode should be limited to 5mA continuous and 30mA peak. An external schottky diode may be used to provide protection when this condition cannot be satisfied. Any ZXCL series device may be used in conjunction with an external PNP transistor to boost the output current capability. In the application circuit shown below, a FMMT717 device is employed as the external pass element. This SOT23 device can supply up to 2.5A maximum current subject to the thermal dissipation limits of the package (625mW). Alternative devices may be used to supply higher levels of current. Note that with this arrangement, the dropout voltage will be increased by the VBE drop of the external device. Also, care should be taken to protect the pass transistor in the event of excessive output current.

Enable Control A TTL compatible input is provided to allow the regulator to be shut down. A low voltage on the Enable pin puts the device into shutdown mode. In this mode the regulator circuit is switched off and the quiescent current reduces to virtually zero (typically less than 10nA) for input voltages above the minimum operating threshold of the device. A high voltage on the Enable pin ensures normal operation. VIN VO R EN C The Enable pin can be connected to VIN or driven from an independent source of up to 10V maximum. (e.g. CMOS logic) for normal operation. There is no clamp diode from the Enable pin to VIN, so the VIN pin may be at any voltage within its operating range irrespective of the voltage on the Enable pin. However input voltage rise time should be kept below 5ms to ensure consistent start-up response. Fig. 1 Circuit Connection Current Limit VIN The ZXCL devices include a current limit circuit which restricts the maximum output current flow to typically 230mA. Practically the range of overcurrent should be considered as minimum 160mA to maximum 800mA. The device's robust design means that an output short circuit to any voltage between ground and VOUT can be tolerated for an indefinite period. VO Td Thermal Overload Thermal overload protection is included on chip. When the device junction temperature exceeds a minimum 125C the device will shut down. The sense circuit will re-activate the output as the device cools. It will then cycle until the overload is removed. The thermal overload protection will be activated when high load currents or high input to output voltage differentials cause excess dissipation in the device. Start up delay Fig. 2 Start Up Delay (Td) Td(NOM ) RC ln VIN V 1.5 IN Calculation of start up delay as above A small amount of hysteresis is provided on the Enable pin to ensure clean switching. This feature can be used to introduce a start up delay if required. Addition of a simple RC network on the Enable pin provides this function. The following diagram illustrates this circuit connection. The equation provided enables calculation of the delay period.

Power Dissipation The maximum allowable power dissipation of the device for normal operation (PMAX), is a function of the package junction to ambient thermal resistance (JA), maximum junction temperature (TJMAX), and ambient temperature (TAMB), according to the expression: PMAX = (TJMAX - TAMB) / JA The maximum output current (IMAX) at a given value of Input voltage (VIN) and output voltage (VOUT) is then given by: IMAX = PMAX / (VIN - VOUT) The value of qja is strongly dependent upon the type of PC board used. Using the SC70 package it will range from approximately 280C/W for a multi-layer board to around 450C/W for a single sided board. It will range from 180C/W to 300C/W for the SOT25 package. To avoid entering the thermal shutdown state, Tjmax should be assumed to be 125C and Imax less than the overcurrent limit, (IOLIM). Power derating for the SC70 and SOT25 packages is shown in the following graph. MAX POWER DISSIPATION (mW) 500 The dielectric of the ceramic capacitance is an important consideration for the ZXCL Series operation over temperature. Zetex recommends minimum dielectric specification of X7R for the input and output capacitors. For example a ceramic capacitor with X7R dielectric will lose 20% of its capacitance over a -40C to +85C temperature range, whereas a capacitor with a Y5V dielectric loses 80% of its capacitance at -40C and 75% at +85C. An input capacitor of 1F (ceramic or tantalum) is recommended to filter supply noise at the device input and will improve ripple rejection. The input and output capacitors should be positioned close to the device, and a ground plane board layout should be used to minimise the effects of parasitic track resistance. Dropout Voltage The output pass transistor is a large PMOS device, which acts like a resistor when the regulator enters the dropout region. The dropout voltage is therefore proportional to output current as shown in the typical characteristics. Ground Current SOT25 The use of a PMOS device ensures a low value of ground current under all conditions including dropout, start-up and maximum load. 300 SC70-5/SOT353 200 Power Supply Rejection and Load Transient Response 100 Line and Load transient response graphs are shown in the typical characteristics. 0 -40 -20 0 20 40 60 TEMPERATURE (C) Derating Curve 80 100 Capacitor Selection and Regulator Stability The device is designed to operate with all types of output capacitor, including tantalum and low ESR ceramic. For stability over the full operating range from no load to maximum load, an output capacitor with a minimum value of 1F is recommended, although this can be increased without limit to improve load transient performance. Higher values of output capacitor will also reduce output noise. Capacitors with ESR less than 0.5V are recommended for best results. ZXCL SERIES Document number: DS33439 Rev. 10 - 3 These show both the DC and dynamic shift in the output voltage with step changes of input voltage and load current, and how this is affected by the output capacitor. If improved transient response is required, then an output capacitor with lower ESR value should be used. Larger capacitors will reduce over/undershoot, but will increase the settling time. Best results are obtained using a ground plane layout to minimise board parasitics. 9 of 13 www.diodes.com November 2015 (c) Diodes Incorporated Not Recommended for New Design: USE: ZXCLxx0E5TA: AP2121AK-x.xTRG1 ZXCLxx0H5TA: AP7115-xxSEG-7 or AP2125KS-X.XTRG1 ZXCL5213VxxH5TA: No Alternative - - ZXCL SERIES Ordering Information ZXCL XXX XX XX Voltage 2.5V: 2.6V: 2.8V: 3.0V: 3.3V: 4.0V: Package 250 260 280 300 330 400 Packing H5 : SC70-5/SOT353 E5 : SOT25 TA : Tape & Reel ZXCL5213V XX XX XX Voltage 2.5V: 2.6V: 2.8V: 3.0V: 3.3V: 4.0V: 25 26 28 30 33 40 Package Packing H5 : SC70-5/SOT353 Device Voltage Packaging Packaging Code Identification Code ZXCL250H5TA 2.5 SC70-5/SOT353 H5 L25A ZXCL260H5TA 2.6 SC70-5/SOT353 H5 TA : Tape & Reel Status - recommended alternative 7" Tape & Reel Quantity NRND - AP7115-25SEG-7 or AP2125KS-2.5TRG1 3000 L26A NRND - No Alternative 3000 3000 ZXCL280H5TA 2.8 SC70-5/SOT353 H5 L28A NRND - AP7115-28SEG-7 or AP2125KS-2.8TRG1 ZXCL300H5TA 3.0 SC70-5/SOT353 H5 L30A NRND - AP7115-30SEG-7 or AP2125KS-3.0TRG1 3000 ZXCL330H5TA 3.3 SC70-5/SOT353 H5 L33A NRND - AP7115-33SEG-7 or AP2125KS-3.3TRG1 3000 ZXCL400H5TA 4.0 SC70-5/SOT353 H5 L40C Obsolete - No Alternative 3000 ZXCL5213V25H5TA 2.5 SC70-5/SOT353 H5 L25C NRND - No Alternative 3000 ZXCL5213V26H5TA 2.6 SC70-5/SOT353 H5 L26C NRND - No Alternative 3000 ZXCL5213V28H5TA 2.8 SC70-5/SOT353 H5 L28C NRND - No Alternative 3000 ZXCL5213V30H5TA 3.0 SC70-5/SOT353 H5 L30C NRND - No Alternative 3000 ZXCL5213V33H5TA 3.3 SC70-5/SOT353 H5 L33C NRND - No Alternative 3000 NRND - No Alternative 3000 NRND - AP2121AK-2.5TRG1 3000 ZXCL5213V40H5TA 4.0 SC70-5/SOT353 H5 L40C ZXCL250E5TA 2.5 SOT25 E5 L25B ZXCL260E5TA 2.6 SOT25 E5 L26B NRND - No Alternative 3000 ZXCL280E5TA 2.8 SOT25 E5 L28B NRND - AP2121AK-2.8TRG1 3000 ZXCL300E5TA 3.0 SOT25 E5 L30B NRND - AP2121AK-3.0TRG1 3000 ZXCL330E5TA 3.3 SOT25 E5 L33B NRND - AP2121AK-3.3TRG1 3000 ZXCL400E5TA 4.0 SOT25 E5 L40B Obsolete - No Alternative 3000 ZXCL SERIES Document number: DS33439 Rev. 10 - 3 10 of 13 www.diodes.com November 2015 (c) Diodes Incorporated Not Recommended for New Design: USE: ZXCLxx0E5TA: AP2121AK-x.xTRG1 ZXCLxx0H5TA: AP7115-xxSEG-7 or AP2125KS-X.XTRG1 ZXCL5213VxxH5TA: No Alternative - - ZXCL SERIES Marking Information SOT25, SC70-5/SOT353 ( Top View ) 5 4 XXXX 1 XXXX : Identification code 2 3 Package Outline Dimensions (All Dimensions in mm) Please see AP02002 at http://www.diodes.com/datasheets/ap02002.pdf for the latest version.
