Revision 2.0

General Description

The MIC5202 is a dual linear voltage regulator with low

dropout voltage (typically 17mV at light loads and 210mV

at 100mA), and low ground current (1mA at 100mA per

output).

Ideal

for

battery-operated

applications,

the

MIC5202 offers 1% output voltage accuracy and dual

enable pins. The enable pins may be driven individually or

consumption drops to nearly zero. The MIC5202 ground

current increases slightly in dropout, which minimizes

power consumption and increases battery life. Some key

features include reversed battery protection, current limit,

and overtemperature protection.

The MIC5202 is available in fixed output voltages in the

small 8-pin SOIC package.

Datasheets and support documentation are available on

Micrel’s web site at: www.micrel.com.
