150 mA LDO with wide input range and low quiescent current
The TPS70930DRVR is a single-output positive LDO regulator delivering a fixed 3 V at up to 150 mA. It accepts inputs up to 30 V, covering 12 V and 24 V industrial rails with margin for transients. Quiescent current is just 2.05 µA typical, making it suitable for always-on or battery-powered circuits where the regulator's own draw must not dominate the sleep budget. The 6-WSON (2x2) package with exposed pad aids thermal dissipation in space-constrained layouts. The pad should be soldered to a copper plane for rated heat transfer.
PSRR profile and protection suite
Power supply rejection ratio measures 80 dB at 10 Hz, rolling off to 52 dB at 1 kHz. This means the LDO attenuates low-frequency ripple from switching converters or line hum by a factor of 10,000 at 10 Hz, dropping to ~400 at 1 kHz — enough to clean up a 24 V industrial bus for sensitive analog loads. Built-in protections include over-current, over-temperature, reverse current, and under-voltage lockout (UVLO). The reverse-current block is notable: if the output is held higher than the input, the LDO does not back-feed the supply rail. Operating temperature spans -40°C to 125°C, qualifying the part for under-hood automotive and outdoor industrial enclosures where ambient heat soaks the board.
Active production and sourcing posture
