Description

The TLV709 low-dropout (LDO) linear voltage regulator is a low quiescent current device. This device offers the benefits of a wide input voltage range and low-power operation in miniaturized packaging. The TLV709 is optimized to power microcontrollers and other low power loads for battery-powered applications.

The TLV709 LDO supports a low dropout of typically 600mV at 100mA of load current. The low quiescent current (3.2µA typically) does not vary across the entire range of output load current (0mA to 150mA). The TLV709 also features an internal soft-start to lower inrush current during start-up. The built-in overcurrent limit protection helps protect the regulator in the event of a load short or fault condition.

The TLV709 is available in 2.9mm × 2.8mm, 5-pin SOT-23 (DBV), 2.92mm × 2.37mm, 3-pin SOT-23 (DBZ), and 4.5mm × 2.5mm, 3-pin SOT-89 (PK) packages, The DBV package is for fixed and adjustable outputs and the DBZ package is only for fixed outputs.
