LD6836CX4/22H,315

Product Overview

The NXP USA Inc. LD6836CX4/22H,315 is a surface-mount, single-output linear voltage regulator providing a fixed positive 2.2 V output from a maximum input of 5.5 V. It is rated for 300 mA and specifies a dropout voltage of 0.16 V at 300 mA. The device integrates an enable control feature and includes overcurrent and overtemperature protection. Its 4-WLCSP package, specified as 0.76x0.76, supports space-constrained surface-mount layouts.

Key Features

• Single-output positive regulator with fixed 2.2 V output and 300 mA output current.
• Maximum input voltage of 5.5 V and dropout voltage of 0.16 V at 300 mA.
• Enable control feature.
• Overcurrent and overtemperature protection.
• PSRR of 55 dB at 1 kHz.
• Quiescent current of 100 µA and maximum supply current of 250 µA.
• Surface-mount 4-XFBGA, WLCSP package with 0.76x0.76 dimensions.
• Operating temperature range of -40°C to 85°C.

Applications

• Fixed-rail regulation for compact electronics.
• Single-output power supply for low-power systems with enable control.
• Board-level voltage regulation in space-limited surface-mount designs.

Design & Procurement Notes

Design considerations include verifying that the input voltage remains within the 5.5 V maximum rating and that the load current does not exceed 300 mA. The 0.16 V dropout specification at 300 mA is relevant when input and output rails are close together, while the 100 µA quiescent current and 250 µA maximum supply current support low-power budget planning. The enable control and protection features should be incorporated into the schematic and layout. The fixed 2.2 V output means the regulator is selected where that voltage is required, and the 4-WLCSP package requires surface-mount assembly with attention to pad layout and the 0.76x0.76 package size.
