General Description
The MIC5231
μ
Cap low-dropout voltage regulator is intended
for low-output-current biasing applications. It features ex-
tremely low ground current, not greater than 4
μ
A under all
load and temperature conditions, making it efficient and ideal
for keep-alive applications in devices such as notebook
computers.
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.
The MIC5231 also features a control pin which allows the
regulator to be shut down when not required. Its shutdown-
state draws zero current, benefitting battery-powered appli-
cations.
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.
