产品概述

TPL700 series product is a high performance and low dropout linear regulator. Current output capability is 300mA.TPL700 series product support low quiescent current and high-PSRR, especially for high frequency. TPL700 series can be stable with output capacitance of 1μF to 10μF with ESR of up to 100mΩ.


The TPL700 series have a high PSRR at high frequency and PSRR can be about 70dB at 2M frequency point. This feature makes TPL700 series very suitable for power-sensitive applications with high noise from front stage power supply.When coupled with a no load quiescent current of 35μA (typical) and 0.1μA shutdown current, the TPL700 series is an ideal choice for portable or wireless equipment. Current-limit and thermal overload protection circuits prevent damage under these conditions. The TPL700 series also includes an internal pull-down resistor on the EN input.


The TPL700 series comes in many fixed voltage options with ±2% output voltage accuracy over temperature, line and load. Other output voltage options are available on request.The TPL700 series is guaranteed over the temperature range of -40°C to +85°C. The TPL700 series of LDOs are available in 3-mm*3-mm SOT23-5 package and SC70-5 package.
