Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ
How does the enable pin function affect power consumption?
Driving the EN pin low activates the built-in auto-discharge feature and reduces quiescent current to a standby level of approximately 1.0µA maximum.
What is the recommended capacitor type for stability?
Low-ESR ceramic capacitors are recommended for both input and output to ensure stability and improve transient response.
