LP3988IMF-3.3/NOPB规格书详情

LP3988IMF-3.3/NOPB属于集成电路(IC)的线性+开关稳压器。由美国德州仪器公司制造生产的LP3988IMF-3.3/NOPB稳压器 - 线性线性稳压器用于提供稳定的输出电压,无论负载电流、输入电压或环境因素如何变化,这些输出电压通常都要保持不变。它们的工作原理要求输入电压维持在高于所需的输出电压,而且要超出某个最小量,并且在工作时会将输入端的任何多余电压转换为热量。对于大多数应用而言,虽然这种稳压器的效率低于开关模式的稳压器,但它们通常更适合对噪声高度敏感的应用。

3 Description

The LP3988 is a 150-mA low dropout regulator

designed specially to meet requirements of portable battery applications. The LP3988 is designed to work

with space-saving, small 1-μF ceramic capacitors.

The LP3988 features a Power Good (PG) output that

indicates a faulty output condition. The device is ideal for mobile phone and similar battery-powered

wireless applications. It provides up to 150 mA output

current from a 2.5-V to 6-V input, consuming less

than 1 μA in disable mode and has fast turnon time

less than 200 μs.

The LP3988 device's performance is optimized for

battery-powered systems to deliver low noise, extremely low dropout voltage, and low quiescent

current. Regulator ground current increases only

slightly in dropout, further prolonging the battery life.

Power supply rejection is better than 60 dB at low frequencies and starts to roll off at 10 kHz. High

power-supply rejection is maintained down to lower

input-voltage levels common to battery-operated

circuits.

The LP3988 is available in a 5-pin SOT-23 package

and a 5-pin thin DSBGA package. Performance is specified for −40°C to +125°C temperature range. For

all available output voltage and package options, see

the Package Option Addendum (POA) at the end of

the data sheet.
