LDK220M33R 200 mA low quiescent current

The adjustable and fixed voltage regulators of the AMS1117 series are designed to deliver 1A output current and function down to 1V input-to-output difference. The device's dropout voltage is guaranteed to be 1.3V at maximum output current, dropping at lower load currents. Trimming on-chip adjusts the reference voltage to one percent. The current limit is also reduced, reducing stress on the regulator and energy source circuitry under overload conditions. The AMS1117 devices are pin compatible with existing three-terminal SCSI regulators and are available in low-profile surface mount SOT-223 packages, 8L SOIC packages, and TO-252 (DPAK) plastic packages.

The voltage regulator supports 2.5V to 13.2V input with very low dropout (100 mV @ 100 mA), low quiescent current

The REF03 precision voltage reference provides a stable 2.5 V output, with minimal change for variations in supply voltage, ambient temperature, or loading conditions. Single-supply operation over an input voltage range of 4.5 V to 33 V with a current drain of 1 mA and good temperature stability is achieved using an improved band gap design. Primarily targeted at price sensitive applications, the REF03 is available in plastic mini DIPs and surface-mount small outline plastic packages. For improved performance or ?40?C to 125?C operation, see the ADR03 data sheet.
