Description
The TPL720 series products are CMOS process low Iq linear
regulators with enable control function. The TPL720 series
products support maximum 400mA output current, with typically
only 1.4 µA ultra-low quiescent current. TPL720 series products
are stable with low-ESR small ceramic output capacitors from
2.2 μF to 10 μF.
The TPL720 series products have fast response performance
when load dynamic drop or raise, especially for the load
dynamic from with some load. The TPL720 series products have
current limit and thermal protection, which improves TPL720
series products with high reliability.
The TPL720 series products have a fixed output voltage range
from 1 V to 3.6 V with ±1% output voltage accuracy, line
regulation and load regulation under room temperature. The
TPL720 series products are guaranteed over the operating
temperature range of −40°C to +85°C. The TPL720 series
products are available in SOT23-3 package, SOT23-5 package,
SOT89-3 package, and 1×1 DFN-4 package.

Regulator enable pin. Drive EN high to turn on the regulator; drive EN low to turn off
the regulator. For automatic startup, connect EN to IN directly.
Ground reference pin. Connect GND pin to PCB ground plane directly.
Input voltage pin. Bypass IN to GND with a 1 μF or greater capacitor.
No connection.
Regulated output voltage pin. Bypass OUT to GND with a 2.2 μF or greater
capacitor.
