3 Description
The LP2985 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 supports an output range of
1.2 V to 5.0 V (for new chip).
Additionally, the LP2985 (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 is available in a 5-pin 2.9-mm × 1.6-mm
SOT-23 (DBV) package.
LP2985-18DBVR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LP2985-18DBVR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。
