UM1560P-30

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

The UM1560P-30 is a positive fixed linear voltage regulator (LDO) manufactured by Union Semiconductor International Limited. It provides a fixed output voltage of 3V with a maximum output current of 300mA. The device operates within an input voltage range of 1.8V to 8V and features a typical low dropout voltage of 250mV at 200mA load. It exhibits a typical quiescent current of 2.5µA when the input voltage is 8V and maintains a low output noise of 115µVRMS over the 10Hz to 10kHz frequency band. The component is available in an SC-82A (SOT-343) package and supports a junction temperature range from -40°C to 125°C.

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

Verify the specific suffix 'P-30' to confirm the 3V fixed output variant, as the UM1560 series includes multiple voltage options. Ensure the package designation matches the required SOT-343 footprint for PCB layout compatibility. Confirm RoHS compliance status if environmental regulations apply to your manufacturing process. Cross-reference the manufacturer's latest datasheet for any updates on recommended operating conditions or pin configurations.

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

Select this component when a stable 3V rail is required from inputs up to 8V with minimal standby current draw. The low dropout characteristic allows efficient regulation even as battery voltage depletes. Consider the thermal performance in the SOT-343 package under high load conditions, as heat dissipation is limited compared to larger packages. Verify that the 115µVRMS noise level meets the sensitivity requirements of downstream analog components.

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

The UM1560 series consists of 8V input, low quiescent current linear regulators designed for efficiency in portable applications. The UM1560P-30 specifically denotes the 3V output version within this family. These regulators are engineered to bridge analog and digital domains by providing clean power with minimal static consumption, making them suitable for modern low-power integrated circuit designs.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Check for direct substitutes such as other 3V LDOs with similar 300mA output and SOT-343 packaging. Verify that alternative parts maintain comparable quiescent current levels and dropout voltages to ensure system efficiency is not compromised during replacement.
