Detailed Description for TPS79118DBVR
Product Overview
Texas Instruments TPS79118DBVR is a linear voltage regulator IC that provides a fixed positive 1.8 V output from a single regulator at up to 100 mA. It accepts an input voltage up to 5.5 V and uses a surface-mount SOT-23-5 package (SC-74A, SOT-753). The device includes an enable control feature and protection functions for over current, over temperature, reverse polarity, and under-voltage lockout. Its quiescent current is 250 µA, and power-supply rejection is 80 dB to 45 dB over 100 Hz to 100 kHz. The operating temperature range is -40°C to 85°C.
Key Features
- Fixed positive 1.8 V output from a single regulator with 100 mA output current
- Maximum input voltage of 5.5 V
- Quiescent current of 250 µA
- Power-supply rejection ratio of 80 dB to 45 dB from 100 Hz to 100 kHz
- Enable control feature
- Over current, over temperature, reverse polarity, and under-voltage lockout protection
- Surface-mount SOT-23-5 package (SC-74A, SOT-753)
Applications
- 1.8 V rail generation for low-current logic or analog loads
- Enable-controlled power management in compact surface-mount assemblies
- Noise-sensitive circuits where input supply rejection over 100 Hz to 100 kHz is relevant
- Systems requiring built-in overcurrent, overtemperature, reverse-polarity, and UVLO protection
Design & Procurement Notes
For design, confirm that the fixed 1.8 V output and 100 mA capability match the load requirement and that the input voltage remains within the 5.5 V maximum. Because the device uses a small surface-mount package, evaluate thermal behavior when the input-to-output voltage difference is large or when operating near 100 mA. Use the enable control to define startup and shutdown behavior, and verify that the control signal is compatible with the circuit. The integrated protections can help manage fault conditions, but the final board should still be checked for current limiting, thermal response, reverse-polarity exposure, and UVLO behavior. The PSRR range should be considered when powering analog or other noise-sensitive loads. For procurement, specify TPS79118DBVR and the SOT-23-5 package to match the board footprint.
