TPS76801

The Texas Instruments TPS76801 is a versatile 1-A, 10-V low-dropout (LDO) voltage regulator. It is engineered for applications requiring fast transient response and stable power delivery.

This regulator supports both adjustable and fixed output voltage options, with a range from 1.2 V to 5.5 V for adjustable outputs and specific fixed voltages available including 1.5 V, 1.8 V, 2.5 V, 2.7 V, 2.8 V, 3.0 V, 3.3 V, and 5.0 V. It operates with an input voltage range of 2.7 V to 10 V and provides a typical dropout voltage of 230 mV at 1 A. The device features an ultralow quiescent current of 85 µA typical.

Key features include an enable pin and an open-drain power good output, providing system monitoring capabilities. The TPS76801 is available in SOIC-8 and HTSSOP-20 packages, suitable for various board space constraints. Its operating temperature range is -40°C to 125°C, making it suitable for demanding environments. Thermal shutdown protection is integrated for device safety.

This LDO is well-suited for power management in a variety of electronic systems where efficient and stable voltage regulation is critical. Its performance characteristics, such as low noise (55 µVrms) and high PSRR (29 dB at 100 KHz), make it a reliable choice for sensitive analog circuits.
