What are the key specifications of the LDK320AM33R?

It supports a 2.5 V to 18 V input, provides 3.3 V output at 200 mA, has a 100 mV dropout voltage, and 88 dB PSRR at 120 Hz.

What should engineers review before using this LDO?

Review the thermal performance (RthJA = 160 °C/W for SOT23-5L) and ensure the output capacitor is a 1 µF ceramic type.

Is this device suitable for battery-powered designs?

Yes, its low quiescent current (60 µA) and shutdown mode (< 1 µA) make it ideal for low-power battery applications.

What is the pinout of LDK320AM33R?

Use the LDK320AM33R datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about LDK320AM33R pinout to locate pins, power rails, and interface signals before layout.
