Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

What is the minimum output capacitance required for stability?

The MCP1700 requires a minimum output capacitance of 1.0 µF to ensure small signal stability.

How does the device handle short-circuit conditions?

Internal circuitry monitors the output current; if a short circuit occurs, the device turns off the pass transistor and attempts to restart automatically once the condition clears.
