The Texas Instruments TPS7A4901 is an adjustable low-dropout (LDO) linear voltage regulator designed for applications requiring low noise and high power supply ripple rejection (PSRR). It can supply up to 150 mA of output current with an input voltage range of 3 V to 36 V.
Key electrical specifications include a low quiescent current of 0.06 mA and a typical dropout voltage of 260 mV at 100 mA. The regulator provides adjustable output voltages from 1.194 V to 33 V with an accuracy of 2.5%. It exhibits low noise, with typical values of 12.7 µVrms (20 Hz to 20 kHz) and high PSRR, reaching 72 dB at 120 Hz.
Features such as a CMOS logic-level-compatible enable pin and soft start functionality are included for enhanced control. The device also incorporates fixed current-limit and thermal shutdown protection for reliability. It is stable with ceramic capacitors of 2.2 µF or greater.
The TPS7A4901 is available in 8-pin HVSSOP PowerPAD and 3-mm x 3-mm VSON packages. It operates within a wide temperature range of -40°C to 125°C, making it suitable for various demanding environments.
