LD6806F/22P,115

Product Overview

The LD6806F/22P,115 from NXP USA Inc. is a single-output linear voltage regulator for fixed positive 2.2 V rail generation in surface-mount power management circuits. The device supports output currents up to 200 mA and specifies a maximum dropout of 0.13 V at 200 mA. It uses a 6-XFDFN package, with a 6-XSON, SOT886 (1.45x1) device package designation, and operates over a -40°C to 85°C temperature range. The regulator includes an enable control and protection against over-current and over-temperature conditions. It has a quiescent current of 100 µA and a power-supply rejection of 55 dB at 1 kHz.

Key Features

• Fixed positive 2.2 V output from a single linear regulator channel
• Maximum input voltage of 5.5 V
• Output current capability of 200 mA
• Maximum dropout voltage of 0.13 V at 200 mA
• Enable control feature for output activation
• Over-current and over-temperature protection features
• Quiescent current of 100 µA and maximum supply current of 250 µA
• Power-supply rejection ratio of 55 dB at 1 kHz
• 6-XFDFN surface-mount package, 6-XSON SOT886 (1.45x1)
• Operating temperature range of -40°C to 85°C

Applications

• Fixed 2.2 V rail generation for low-current analog or mixed-signal board sections
• Controlled power delivery to sensor or peripheral subsystems requiring a 2.2 V supply
• Enable-controlled power management in compact surface-mount assemblies

Design & Procurement Notes

When selecting LD6806F/22P,115 for a 2.2 V rail, verify that the available input remains within the 5.5 V maximum and that headroom accounts for the 0.13 V maximum dropout at 200 mA. The enable function can be used to control regulator output during power sequencing, while over-current and over-temperature protection support operation within the -40°C to 85°C range. The 6-XFDFN / 6-XSON SOT886 (1.45x1) footprint should be considered in dense board layouts, and the 100 µA quiescent current and 55 dB PSRR at 1 kHz can help assess noise and standby power budgets.
