TPS78236DDCR

Product Overview

The TPS78236DDCR from Texas Instruments is a surface-mount linear voltage regulator that provides one positive fixed 3.6 V output. The device is specified for a maximum input voltage of 5.5 V and an output current of 150 mA, with a dropout voltage of 0.25 V at 150 mA. It uses a thin SOT-23-5 package and includes an enable control feature, over-current, over-temperature, and reverse-polarity protection. The specified operating temperature range is -40°C to 125°C, and the quiescent current is 1.3 µA.

Key Features

• Single positive fixed 3.6 V output.
• Maximum input voltage of 5.5 V.
• Output current of 150 mA.
• Dropout voltage of 0.25 V at 150 mA.
• Quiescent current of 1.3 µA and maximum supply current of 8 µA.
• Enable control feature.
• Over-current, over-temperature, and reverse-polarity protection.
• PSRR of 40 dB to 15 dB from 10 Hz to 1 kHz.
• Surface-mount SOT-23-5 Thin, TSOT-23-5 package.
• Operating temperature range of -40°C to 125°C.

Applications

• Fixed 3.6 V rail for compact sensor modules and low-current board subsystems.
• Embedded logic or peripheral power supplies that require enable control.
• Power rails sensitive to supply noise where the specified PSRR range is relevant.
• Space-constrained surface-mount designs using a thin SOT-23-5 package.

Design & Procurement Notes

For design use, confirm that the input voltage remains within the 5.5 V maximum and provides enough headroom above 3.6 V under load, considering the 0.25 V dropout specification at 150 mA. The fixed 3.6 V output and 150 mA limit align with low-current rail requirements, while the enable control feature allows output operation to be controlled. The thin SOT-23-5 surface-mount package should be checked against the board footprint and assembly process. For noise-sensitive rails, the PSRR of 40 dB to 15 dB from 10 Hz to 1 kHz can guide placement relative to noisy supply sources. The specified operating temperature range is -40°C to 125°C. For procurement, match the exact manufacturer part number TPS78236DDCR and the thin SOT-23-5 package to avoid footprint mismatches.
