3 Description
The LP2985-N is a fixed-output, wide-input, low-noise,
low-dropout voltage regulator supporting an input
voltage range from 2.5 V to 16 V and up to 150 mA of
load current. The LP2985-N supports an output range
of 1.2 V to 5.0 V (new chip) and 2.5 V to 6.1 V (legacy
chip).
Additionally, the LP2985-N (new chip) has a 1
output accuracy across load and temperature that
can meet the needs of low-voltage microcontrollers
(MCUs) and processors.
Low output noise of 30 μVRMS (with 10-nF bypass
capacitors) and wide bandwidth PSRR performance
of greater than 70 dB at 1 kHz and 40 dB at 1 MHz
help attenuate the switching frequency of an upstream
DC/DC converter and minimize post regulator filtering.
The internal soft-start time and current-limit protection
reduce inrush current during start up, thus minimizing
input capacitance. Standard protection features, such
as overcurrent and overtemperature protection, are
included.
The LP2985-N is available in a 5-pin, 2.9-mm × 1.6-
mm SOT-23 (DBV) package.
LP2985IM5-2.9/NOPB属于集成电路(IC) > 线性 + 开关稳压器。美国德州仪器公司制造生产的LP2985IM5-2.9/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。
