The MIC5157YN from Microchip Technology is a Super Low-Dropout (LDO) Regulator Controller designed for high-current linear voltage regulation applications. This IC utilizes an external N-channel power MOSFET as the linear pass element, allowing for dropout voltages as low as the MOSFET's Rds(on) multiplied by the output current.
The device operates from an input voltage range of 3V to 36V. The MIC5157YN features an internal charge pump voltage tripler to generate the necessary gate drive voltage for the external MOSFET. It offers a programmable output voltage range from 1.3V to 36V, configurable using two external resistors. The controller includes an enable pin for activating or shutting down the regulator, reducing standby current to less than 1µA.
Key electrical specifications include a typical operating current of 4.5mA and an output voltage tolerance of 1% initial and 2% over temperature. The MIC5157YN is available in a 14-pin DIP package and operates within a temperature range of -40°C to +85°C.
This controller is suitable for applications such as ultrahigh current ultralow dropout voltage regulators, constant high-current sources, and low parts count power supplies.
