Detailed Description for TPS78319DDCR
Product Overview
The TPS78319DDCR from Texas Instruments is a single-output linear voltage regulator that provides a fixed positive 1.9 V output at up to 150 mA. The device accepts a maximum input voltage of 5.5 V and includes an enable control feature, which allows the regulator to be turned on or off by an external control signal. It is supplied in a surface-mount SOT-23-5 Thin / TSOT-23-5 package and is specified for operation from -40°C to 105°C.
Key Features
- Single positive fixed 1.9 V output with an output current of 150 mA
- Maximum input voltage of 5.5 V
- Quiescent current of 800 nA and maximum supply current of 8 µA
- Enable control feature for external power-state management
- Protection features include over current, over temperature, and reverse polarity
- PSRR specified as 40 dB to 15 dB from 10 Hz to 1 kHz
- Operating temperature range of -40°C to 105°C
- Surface-mount SOT-23-5 Thin / TSOT-23-5 package
Applications
- Generating a fixed 1.9 V output for low-current circuits that require a regulated positive supply
- Using the enable control feature to manage when the regulator is active in a system
- Applying the 800 nA quiescent current specification in designs where regulator input current must be minimized
- Employing over current, over temperature, and reverse polarity protection in a single-output power distribution path
Design & Procurement Notes
When selecting the TPS78319DDCR, verify that the system supply remains within the specified maximum input voltage of 5.5 V and that the load current does not exceed the 150 mA output rating. The fixed 1.9 V output means the regulator is intended for designs that require a single predetermined voltage rather than an adjustable output. The enable control feature should be connected appropriately in the schematic if controlled power-up or power-down is required. Because the device is specified from -40°C to 105°C and includes over temperature and over current protection, thermal headroom and fault response should still be evaluated in the final layout. The SOT-23-5 Thin / TSOT-23-5 surface-mount package requires a compatible footprint.
