ADP162ACBZ-2.3-R7

Ultralow Quiescent Current,150 mA, CMOS Linear Regulators

Analog Devices 

Data Sheet

To minimize quiescent current in the ADP161 and ADP163

Analog Devices, Inc., recommends using high values of

resistance for R1 and R2. Using a value of 1 MΩ for R2 keeps

the total, no load quiescent current below 2 µA. Note however,

that high value of resistance introduces a small output voltage

error. For example, assuming R1 and R2 are 1 MΩ, the output

voltage is 2 V. Taking into account the nominal ADJ pin bias

current of 10 nA, the output voltage error is 0.25%.

Note that in shutdown, the output is turned off and the divider

current is zero.

ADP160/ADP161/ADP162/ADP163

The ADP160/ADP161 also include an output discharge resistor to

force the output voltage to zero when the LDO is disabled. This

ensures that the output of the LDO is always in a well-defined state,

whether it is enabled or not. The ADP162/ADP163 do not

include the output discharge function.

The ADP160/ADP162 are available in 15 output voltage options,

ranging from 1.2 V to 4.2 V. The ADP16x use the EN pin to enable

and disable the VOUT pin under normal operating conditions.

When EN is high, VOUT turns on, and when EN is low, VOUT

turns off. For automatic startup, EN can be tied to VIN.
