Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify component authenticity through authorized channels as datasheet information originates from austriamicrosystems AG. Confirm package integrity and pin alignment against the 8-pin TDFN 2x2 specifications prior to assembly. Ensure environmental conditions remain within the specified -40°C to +85°C operating range.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this model for applications requiring a precise 3.0V fixed output without external resistor dividers. Consider the 150mA maximum current limit and 110mV dropout voltage when designing for battery-powered systems near end-of-life discharge curves. Verify that the required PSRR meets system noise requirements at target frequencies.

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

How does the AS1367 achieve high efficiency across varying loads?

It utilizes adaptive operation to automatically switch between light-load and heavy-load modes depending on the instantaneous output current level.

What happens to the output voltage when the Enable pin is deactivated?

An internal auto-discharge resistance discharges the charge stored at the output capacitor, causing the VOUT pin to quickly return to the GND level.
