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

Verify the component status as obsolete or end-of-life through official manufacturer channels before procurement planning. Confirm that the specific ordering code matches the required 3.3V fixed output variant. Ensure compatibility with the 3-pin SOT23 footprint and validate that the application environment remains within the specified -40°C to +85°C operating temperature range.

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

Select this regulator for portable applications requiring minimal standby power draw. The device is suitable where a stable 3.3V rail is needed from higher voltage sources like alkaline batteries. Consider the thermal resistance characteristics when designing PCB layouts for high ambient temperatures or maximum load currents to ensure junction temperature limits are not exceeded.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This component belongs to the AS1360 series of low-power linear regulators produced by ams-OSRAM (formerly austriamicrosystems). The series offers various fixed output voltages including 1.8V, 2.1V, 2.5V, 3.0V, 3.3V, and 5.0V. All variants share the same low quiescent current architecture and protection features, differing primarily in their internal resistor divider networks for output voltage setting.
