The standout feature is the 1uA quiescent current, making it ideal for always-on battery-powered applications where minimal standby power consumption is critical. The device accepts input voltages from 5.35V to 36V, providing wide headroom for automotive and industrial applications. Reverse current protection prevents current flow from output to input, eliminating the need for external blocking diodes. The active-high enable pin allows the device to be placed in a near-zero current shutdown mode. Thermal shutdown and overcurrent protection ensure robust operation under fault conditions. The TPS70950 is available in a 6-pin SOT-23 (DRV) package rated for -40 to 125 C.","working_principle":"The TPS70950DRVR operates as a PMOS LDO with ultra-low quiescent current design. Key subsystems include: (1) Voltage Reference - an internal sub-bandgap reference achieves 1uA quiescent current operation; (2) Error Amplifier - a low-power error amplifier compares the feedback voltage with the internal reference and drives the PMOS gate; (3) PMOS Pass Element - a P-channel MOSFET provides regulation with 350mV dropout at 150mA; (4) Reverse Current Protection - an internal circuit blocks current flow from output to input when VOUT exceeds VIN, preventing damage to upstream circuits; (5) Enable Logic - active-high enable controls device operation with near-zero current in shutdown; (6) Protection - thermal shutdown and current limiting protect under fault conditions.","pin_description":"
