05% typical Under-voltage lockout and softstart Over Temperature protection T0-252 DPAK, 5-lead SPAK packages Fixed 3.
3V and adjustable or fixed 2.
5V output General Description The FAN1538 provides two output voltages: a fixed 3.
3V ouput and either a fixed 2.
5V or adjustable output with 1A output current capability.
Refer to Ordering Information for details.
Current limit protects against short circuit currents and on chip over temperature circuitry limits the maximum die temperature.
Under voltage lockout and softstart circuitry protects against unregulated output voltages when the input voltage is below specification.
