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.
