DATA SHEET BIPOLAR ANALOG INTEGRATED CIRCUIT PC2933A, 2905A THREE-TERMINAL LOW DROPOUT VOLTAGE REGULATOR DESCRIPTION The PC2933A, 2905A of low dropout voltage three terminal positive regulators is constructed with PNP output transistor. The PC2933A, 2905A feature the ability to source 1 A of output current with a low dropout voltage of typically 0.7 V. The power dissipation of the PC2933A, 2905A can be drastically reduced compared with the conventional three terminal positive voltage regulators that is constructed with NPN output transistor. Also, this series corresponds to the low voltage output (3 V, 3.3 V) which is not in the conventional low dropout regulators ( PC2400A series). FEATURES * Output current in excess of 1.0 A * Low dropout voltage VDIF = 0.7 V TYP. (at IO = 1 A) * On-chip overcurrent and thermal protection circuit * On-chip output transistor safe area protection circuit PIN CONFIGURATION (Marking Side) PC2933AHF, 2905AHF : MP-45G PC2933AHB, 2905AHB : MP-3 PC2933AT, 2905AT : MP-3Z 4 1 2 3 1 2 3 1: INPUT 2: GND 3: OUTPUT 1: INPUT 2: GND 3: OUTPUT 4: GND (Fin) The information in this document is subject to change without notice.

When the operating junction temperature rises over 150C, the internal circuit shuts down the output voltage. Caution If the absolute maximum rating of any of the above parameters is exceeded even momentarily, the quality of the product may be degraded. In other words, absolute maximum ratings specify the values exceeding which the product may be physically damaged. Be sure to use the product with these ratings never exceeded. STANDARD CONNECTION D1 PC2933A, 2905A INPUT CIN OUTPUT + COUT D2 CIN: 0.1 F or higher. Set this value according to the length of the line between the regulator and INPUT pin. Be sure to connect CIN to prevent parasitic oscillation. Use of a film capacitor or other capacitor with excellent voltage and temperature characteristics is recommended. If using a laminated ceramic capacitor, it is necessary to ensure that CIN is 0.1 F or higher for the voltage and temperature range to be used. COUT: 47 F or higher. Be sure to connect COUT to prevent oscillation and improve excessive load regulation. Place CIN and COUT as close as possible to the IC pins (within 2 cm). Also, use an electrolytic capacitor with low impedance characteristics if considering use at sub-zero temperatures. D1: If the OUTPUT pin has a higher voltage than the INPUT pin, connect a diode. D2: If the OUTPUT pin has a lower voltage than the GND pin, connect a Schottky barrier diode. Caution Make sure that no voltage is applied to the OUTPUT pin from external. 4 Data Sheet G15374EJ2V0DS PC2933A, 2905A RECOMMENDED OPERATING CONDITIONS Parameter Symbol Type Number MIN. TYP. MAX.

Through-hole devices PC2933AHF, 2905AHF: MP-45G PC2933AHB, 2905AHB: MP-3 Process Conditions Wave soldering Solder temperature: 260C or below, (only to leads) Flow time: 10 seconds or less. Partial heating method Pin temperature: 300C or below, Heat time: 3 seconds or less (Per each pin). Caution For through-hole device, the wave soldering process must be applied only to leads, and make sure that the package body does not get jet soldered. 12 Data Sheet G15374EJ2V0DS PC2933A, 2905A NOTES ON USE When the PC2933A, 2905A are used with an input voltage that is lower than the value indicated in the recommended operating conditions, a large quiescent current flows through the device due to saturation of the transistor of the output stage. (Refer to the IBIAS (IBIAS(S)) vs. VIN curves in TYPICAL CHARACTERISTICS). These products have saturation protector, but a current of up to 80 mA MAX. may flow through the device. Thus the power supply on the input side must have sufficient capacity to allow this quiescent current to pass when the device starts up.
