150-mA 24-V ultra-low-IQ low-dropout voltage regulator for 3 V and 3.3 V

TLV70133DBVR General Description

The TLV701 low-dropout (LDO) linear voltage regulator is a low quiescent current device that offers the benefits of a wide input voltage range and low-power operation in miniaturized packaging. Thus, the TLV701 is designed for battery-powered applications and as a power-management attachment to low-power microcontrollers.

The TLV701 LDO supports a low dropout of typically 850 mV at 100 mA of load current. The low quiescent current (3.4 µA typically) is stable over the entire range of output load current (0 mA to 150 mA). The TLV701 also features an internal soft-start to lower the inrush current. The built-in overcurrent limit protection helps protect the regulator in the event of a load short or fault.

The TLV701 is available in a 2.90-mm × 1.60-mm SOT23-5 package, which is useful for cost-effective board manufacturing.
