Ultra Low Output Voltage Linear N-FET Controller AP2160
Preliminary Datasheet
General Description
The AP2160 is an ultra low output voltage N-FET
linear regulator controller. The output voltage can be
adjusted down to 0.5V. A Power-On-Reset (POR)
circuit monitors supply voltage to prevent wrong
operations. A POK pin indicates the output status. It
can control other converters for power sequence. The
AP2160 can be enabled by other power systems.
The AP2160 integrates a 0.5V reference voltage with
1% accuracy to provide tight regulation to the output
voltage. The regulator also features enable control,
open drain power good signal, under-voltage
protection and soft start.
The AP2160 is available in 6-pin SOT-23-6 standard
package.
