The device delivers up to 150 mA and is available with preset output voltages of 1.25 V, 1.6 V, 1.8 V, 2.0 V, 2.2 V, 2.4 V, and 2.6 V, 2.8 V, 3.0 V, and 3.3 V for both SOT 23-5 and WL-CSP packages. Bias Circuit The bias block provides bias currents and voltages for the other blocks. It has a self start-up circuit and it can establish the bias currents and voltages very fast. Temperature Sensor The temperature sensor block monitors the die temperature and flags Power OK when the temperature crosses 133 C. If the die temperature goes beyond 165 C typical value the output amplifier is shut down. Both the temperatures corresponding to PWROK or PWRON have a hysteresis of 10 C. The 1.25 band-gap reference is connected to the error amplifier's inverting input. The error amplifier compares this reference with the feedback voltage and amplifies the difference. If the feedback voltage is lower than the reference voltage, the pass-transistor gate is pulled lower, which allows more current to pass to the output. The output voltage is fed back through an internal resistor voltage divider connected to the Vout pin. Reverse Battery Protection The reverse battery protection circuit prevents damage to the device if the supply battery is accidentally installed backwards. This circuit compares VIN and PWRON to ground and disconnects the device's internal circuits if it detects reversed polarity. Reverse supply current is limited to 1mA when this protective circuit is active, preventing the battery from rapidly discharging through the device. Reverse battery current is extremely low, 0.5 mA typical. Band-gap The band-gap circuitry generates a temperature independent voltage by properly adding two voltages with negative and positive temperature coefficient. The band-gap voltage is typically 1.25 volts with a temperature variation of 5 mV over the temperature range from -40 C to 125 C. PWROK Output Low Pass Filter PWROK goes low when the output voltage goes out of regulation as during drop-out, current limit or thermal shutdown. PowerOK is an open-drain N-channel MOSFET. To obtain a logic-level output, connect a 10 k pull-up resistor from PWROK pin to VOUT pin. To minimize current consumption, make this resistor as large as practical. A 100 k resistor works well for most applications. The PowerOK is not active during shutdown. PWROK has a 10 s blanking time to allow transient responses to settle within accuracy limits. Low pass filter is basically an RC filter with a low cutoff frequency. No external capacitor is used. There is one comparator, which turns on the bypass paths to charge or discharge the capacitor if the output of the filter is higher or lower than the band-gap voltage by a specified amount. Output Amplifier The output amplifier is a folded cascode PMOS amplifier which controls the gate of the output transistor and sources the load current. A portion of the output voltage is compared to the reference voltage and a constant voltage is maintained at output. The output is also monitored by a comparator which trips the PWROK if the output voltage falls below the nominal output level by a specified amount due to low battery condition or any other reason. The current limiter circuit monitors the output current and limits the load current to a certain value to avoid any damage due to short circuit. 2003 Aug 27 Current Limit The SA57017 includes a current limiter that monitors and controls the pass transistor's gate voltage, limiting the output current to 300 mA typical value. For design purposes, consider the current limit to be 160 mA minimum value. The output can be shorted to ground for an indefinite period of time without damaging the part. 8 Philips Semiconductors Product data CapFREE 150 mA, low-noise, low-dropout regulator with thermal protection SA57017-XX SIMPLIFIED BLOCK DIAGRAM PWRON 3 REVERSE BATTERY PROTECTION TEMP.
