TLV705中文资料具有低噪声和使能功能的 200mA、高 PSRR、低 IQ、低压降稳压器数据手册TI规格书

描述 Description

The TLV705 series of low-dropout (LDO) linear regulators are low quiescent current devices with excellent line and load transient performance. These devices are designed for power-sensitive applications, with a precision band gap. An error amplifier provides typical accuracy of 0.5%. Low output noise, very high power-supply rejection ratio (PSRR), and low dropout voltage make this series of LDOs ideal for a wide selection of battery-operated handheld equipment. All devices have a thermal shutdown and current limit for safety.

Furthermore, the TLV705 series is stable with an effective output capacitance of only 0.1 µF. This feature enables the use of cost-effective capacitors that have higher bias voltage and temperature derating. The devices regulate to the specified accuracy with zero output load. The TLV705P series also provides an active pulldown circuit to quickly discharge output.

The TLV705 and TLV705P series are both available in 0.77-mm × 0.77-mm DSBGA and PicoStar packages with three height options that are optimal for handheld applications.
