Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for MIC5271BM5-TR
Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview
The MIC5271BM5-TR is a fixed negative µCap low-dropout regulator manufactured by Microchip Technology. It provides a stable -3.0V output with ±2% initial accuracy and sinks up to 100mA of load current. The device operates within an input voltage range of –16V to –3.3V and features a typical dropout voltage of –500mV at full load. Designed for space-constrained applications, it utilizes a 5-pin SOT23 package and includes thermal shutdown and current-limit protection.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ
What is the minimum output capacitance required for stability?
A minimum of 1µF output capacitance is required. The device is stable with low-ESR ceramic or tantalum capacitors.
How does the enable pin function?
The enable pin is TTL logic-compatible. Applying a voltage higher than the negative threshold or lower than the positive threshold turns the regulator on; otherwise, it enters a zero-current off mode.
