Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for LP3878SD-ADJ/NOPB

LP3878SD-ADJ/NOPB

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

The LP3878SD-ADJ/NOPB is a micropower, low-noise adjustable linear voltage regulator manufactured by Texas Instruments. It delivers an output current of 800mA with a maximum dropout voltage of 1.1V at full load. The device supports an input voltage range up to 16V and provides an adjustable output voltage between 1V and 5.5V. It features a typical quiescent current of 1.5 mA and offers high power supply rejection ratio (PSRR) of 60dB at 1kHz. The component is housed in an 8-WSON package with exposed pad and operates within a temperature range of -40°C to 125°C.

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

Verify the specific suffix NOPB indicates lead-free/RoHS compliance when sourcing. Confirm the 8-WSON package dimensions match the PCB footprint requirements. Ensure the ordering quantity aligns with the manufacturer's standard tape and reel specifications to avoid packaging discrepancies during assembly.

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

Select this component for applications requiring low noise and micropower consumption in a compact surface-mount package. Compare against the LP38798 series if higher PSRR or lower dropout voltage is required. Verify that the external feedback resistor network can achieve the desired output voltage within the 1V to 5.5V range while maintaining stability with the chosen output capacitor.

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

This part belongs to the LP3878 family of LDO regulators from Texas Instruments. It shares functional similarities with other members like the LP3878MR variant but differs in package type, utilizing an 8-WSON form factor instead of PowerSOIC. The family is designed for portable electronics where space and power efficiency are critical constraints.

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

LP3878MR-ADJ/NOPB is a pin-compatible alternative in a different package. LP38798SD-ADJ/NOPB offers improved performance metrics but requires design review due to parameter differences.
