MIC5231

Micropower µCap LDO Regulator

General Description

Features

The MIC5231 µCap low dropout voltage regulator is

intended for low output current biasing applications. It

features extremely low ground current, not greater than

4µA under all load and temperature conditions, making it

efficient and ideal for keep-alive applications in devices

such as notebook computers.

• Extremely low quiescent current—only 0.65µA

• No output capacitor requirement

• Stable with ceramic or tantalum capacitors

• IttyBitty^®SOT-23-5 surface-mount package

• 10mA output drive

• Low 150mV at 10mA dropout voltage

• Tight load and line regulation

• Low temperature coefficient

The MIC5231 offers better than 2% initial accuracy and

low dropout (typically 150mV at 10mA output current). An

output capacitor is not required for stable operation,

decreasing cost and board space. Tiny ceramic chip

capacitors may be used to improve transient response.

• Logic-level enable input

The MIC5231 also features a control pin which allows the

regulator to be shut down when not required. Its shutdown-

state draws zero current, benefiting battery-powered appli-

cations.

Applications

• Real-time clocks

• SRAM backup

• Cellular telephones

• Laptop, notebook and palmtop computers

• Battery-powered equipment

• Bar code scanners

The MIC5231 is available in fixed output voltages of 2.75V,

3.0V, 3.3V and 5V in the small SOT-23-5 IttyBitty^®

package. Contact Micrel for other voltage options.

Data sheets and support documentation can be found on

Micrel’s web site at: www.micrel.com.

• SMPS post-regulator and DC-to-DC modules
