LD6816CX4/13P,315

Product Overview

The LD6816CX4/13P,315 from NXP USA Inc. is a positive fixed-output linear voltage regulator that provides a 1.3 V output at up to 150 mA. The maximum input voltage is 5.5 V, and the maximum dropout voltage is 0.075 V at 150 mA. The regulator includes an enable control and protection against over-current, over-temperature, and transient-voltage conditions. It is packaged in a 4-XFBGA, WLCSP surface-mount package with a 0.76 mm x 0.76 mm footprint and is rated for an operating temperature range of -40°C to 85°C.

Key Features

• Single positive fixed output regulator with a 1.3 V output and a 5.5 V maximum input.
• 150 mA output current with 0.075 V maximum dropout at 150 mA.
• Enable control for managed output activation.
• Over-current, over-temperature, and transient-voltage protection.
• 100 µA quiescent current and 250 µA maximum supply current.
• PSRR of 55 dB at 1 kHz.
• 4-XFBGA, WLCSP surface-mount package with 0.76 mm x 0.76 mm dimensions.
• Operating temperature range of -40°C to 85°C.

Applications

• Regulating a single 1.3 V rail for low-current logic, sensor, or peripheral circuits.
• Providing controlled power delivery in battery-operated portable electronics.
• Supporting compact board layouts where a small WLCSP linear regulator is needed.

Design & Procurement Notes

Design considerations include input voltage headroom, since the maximum input voltage is 5.5 V and the dropout voltage is 0.075 V at 150 mA. The fixed 1.3 V output and 150 mA output current limit require the load to remain within that current range. The enable control can be used to turn the output on or off, while the over-current, over-temperature, and transient-voltage protections address fault conditions. The 100 µA quiescent current and 250 µA maximum supply current are relevant for low-power budgets. Layout should account for the 4-XFBGA, WLCSP surface-mount package and the -40°C to 85°C operating range.
