TPS78227DDCR Description

Short technical summary and product information.

The TPS78227DDCR by Texas Instruments is a fixed-output, positive-voltage linear regulator designed for low-power applications. It delivers up to 150 mA of output current with a typical dropout voltage of only 130 mV at 150 mA at 25°C, and 175 mV at 85°C, enabling efficient regulation even with small input-to-output voltage differences.

 

Key electrical characteristics include an input voltage range of 2.2 V to 5.5 V, a quiescent current of 500 nA, and output voltage accuracy of 3% over load, line, and temperature. The device features power-supply rejection ratio of 40 dB down to 15 dB across 10 Hz to 1 kHz, and operates over a junction temperature range of -40°C to 125°C.

 

The regulator is equipped with an enable control feature and includes protection against over-current, over-temperature, and reverse polarity conditions. It is offered in a SOT23-5 package, suitable for space-constrained designs. Typical applications include battery-powered equipment, portable electronics, and other low-power systems requiring a stable 2.7V rail.
