LD6816CX4/28P,315 詳細描述

Product Overview

The LD6816CX4/28P,315 from NXP USA Inc. is a fixed-output linear voltage regulator designed to provide a positive 2.8V output from an input voltage up to 5.5V maximum. It supplies up to 150mA from a single output and is packaged in a 4-WLCSP, 0.76mm x 0.76mm, for surface-mount assembly. The device includes an enable control and protection against over current, over temperature, and transient voltage. Its specified quiescent current is 100µA, with maximum supply current of 250µA, and it operates from -40°C to 85°C. A dropout voltage of 0.075V at 150mA and PSRR of 55dB at 1kHz support low-current regulation in compact designs.

Key Features

Fixed positive 2.8V output with 150mA maximum output current.
Input voltage up to 5.5V maximum.
Low dropout voltage of 0.075V at 150mA.
Quiescent current of 100µA and maximum supply current of 250µA.
Enable control for output on/off management.
Protection features include over current, over temperature, and transient voltage.
PSRR of 55dB at 1kHz.
4-WLCSP surface-mount package measuring 0.76mm x 0.76mm.
Operating temperature range from -40°C to 85°C.

Applications

Portable battery-powered devices needing a compact 2.8V supply for low-current logic or sensor circuits.
Embedded modules where an enable signal controls a local regulator rail during standby or power sequencing.
Space-constrained PCBs using a 0.76mm x 0.76mm WLCSP package for small product enclosures.
Low-power subsystems where 100µA quiescent current and 150mA output current match small load requirements.
Analog or digital interfaces requiring a fixed 2.8V supply with over current and over temperature protection.

Design & Procurement Notes

Designers should confirm that the input voltage does not exceed the 5.5V maximum and that the selected input provides sufficient headroom for the 0.075V dropout at 150mA. The fixed 2.8V output is suitable only for loads within the 150mA output limit, so margin should be considered for peak currents. The enable control can be used to place the regulator in a controlled off state when the rail is not required, while the 100µA quiescent current supports low-power operation. Because the device uses a 4-WLCSP, 0.76mm x 0.76mm package, board layout should account for the small surface-mount footprint. The -40°C to 85°C operating range and specified protections should be checked against the final assembly environment and load behavior.
