Pin Function
Supply Input (VIN1 and VIN2 are internally tied together.)
Enable Input for Regulator 1: Regulator 2 internally enabled when regulator
1 reaches 90% of nominal output. Active High input.
Not internally connected.
Reference Bypass: Connect external 0.01µF to GND to reduce output noise.
May be left open.
Active high signal drives open-drain N-channel MOSFET.
Adjust Input (Regulator 1): Connect feedback resistors to program the
output voltage for the regulator.
Delay Set Input: Connect external capacitor to GND to set the internal delay
for the POR output. When left open, there is no delay. This pin cannot be
grounded.
Ground: Connect externally to Exposed Pad.
Ground for the open-drain driver. Tied to the source of the NMOSFET. Tied
to GND internally.
Adjust Input (Regulator 2): Connect feedback resistors to program the
output voltage for the regulator.
Open-Drain Output: Capable of sinking 150mA.
Power-On Reset Output: Open-drain output. Active low indicates an output
undervoltage condition on regulator 2.
Output of Regulator 2: 300mA output current
Output of Regulator 1: 150mA output current
Ground: Internally connected to the Exposed Pad. Connect externally to
ground pin.
