Description

The TPL720 is a series of CMOS process low Iq linear

regulators with enable control function. The TPL720 series

supports a maximum 400-mA output current, with typically

only a 1.4-μA ultra-low quiescent current. TPL720 series is

stable with low-ESR small ceramic output capacitors from

2.2 μF to 10 μF.

The TPL720 series has fast response performance when

the load current dynamic drops or rises, especially for the

load-current dynamic from some load. The TPL720 series

has a current limit and thermal protection, which improves

the TPL720 series with high reliability.

The TPL720 series has a fixed output voltage range from

1 V to 3.3 V with ±1% output voltage accuracy, line

regulation, and load regulation under room temperature.

The TPL720 series is guaranteed over the junction

temperature range of −40°C to +125°C. The TPL720

series is available in the SOT23-3, SOT23-5, and SOT89-3

packages.
