Status: In Production
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.
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 line 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 applications.
The MIC5231 is available in fixed output voltages of 2.75V, 3.0V, 3.3V, and 5.0V in the small SOT-23-5 IttyBitty® package. Contact Micrel for other voltage options.
