LD6836CX4/16P,315

Product Overview

The LD6836CX4/16P,315 from NXP USA Inc. is a positive fixed-output linear voltage regulator intended for compact surface-mount power management. It provides a single 1.6V output at up to 300mA, with a maximum input voltage of 5.5V and a maximum dropout voltage of 0.16V at the rated output current. The device is housed in a 4-XFBGA, WLCSP package with 0.76x0.76 dimensions, and it operates over a -40°C to 85°C temperature range. It includes an enable control and protection against over-current and over-temperature conditions.

Key Features

• Fixed 1.6V positive output with 300mA output current capability.
• Maximum input voltage of 5.5V and maximum dropout voltage of 0.16V at 300mA.
• Quiescent current of 100 µA and maximum supply current of 250 µA.
• 55dB PSRR at 1kHz for input ripple attenuation.
• Enable control feature plus over-current and over-temperature protection.
• Surface-mount 4-XFBGA, WLCSP package with 0.76x0.76 dimensions.

Applications

• 1.6V rail generation for embedded systems and compact circuit boards.
• Regulated supply for logic, sensors, or analog circuits requiring a fixed positive voltage.
• Enable-controlled output activation in power-managed boards.

Design & Procurement Notes

Design considerations should focus on the 5.5V maximum input, the 1.6V fixed output, and the 300mA load limit. The 0.16V maximum dropout at 300mA sets a headroom requirement for input-to-output voltage under full load. The enable control feature can be used for controlled output activation, while over-current and over-temperature protection should be considered as device-level safeguards rather than substitutes for system-level protection. The 4-XFBGA, WLCSP package requires surface-mount assembly and attention to layout constraints within the -40°C to 85°C operating range.
