philips semiconductors product data sa57016-xx capfree ? 150 ma, low-noise, ultra low-dropout regulator with thermal protection 2003 dec 12 6 technical discussion the sa57016 is a low drop-out, low-quiescent current linear regulator designed primarily for battery-powered applications and stabilizes with or without input/output capacitors. 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, 2.6 v, 2.8 v, 3.0 v, and 3.3 v for wl-csp packages. 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 v out pin. 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. low-pass filter low-pass filter is basically an rc filter with a low cut-off 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. 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. thermal shutdown protection the temperature sensor block monitors the die temperature. if the die temperature goes beyond 163 c typical value, the output amplifier is shut down with a hysteresis of 10 c. reverse battery protection the reverse battery protection circuit prevents damage to the device if the supply battery is accidentally installed backwards. this circuit compares v in and pwron to ground and disconnects the device's internal circuits if it detects reversed polarity. reverse supply current is limited to 1 ma when this protective circuit is active, preventing the battery from rapidly discharging through the device. reverse battery current is extremely low, 0.5 m a typical. current limit the sa57016 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. pwrok output the power ok and temperature warning features are offered in the sa57017 family and pin-for-pin compatible to lp3988 with better performance. please contact philips local sales department for further information.
