Ultra Low Output Voltage Linear N-FET Controller AP2160

Jan. 2012 Rev. 1. 0 BCD Semiconductor Manufacturing Limited

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.
