TPS76201DBVR集成电路（IC）的线性+开关稳压器规格书PDF中文资料

TPS76201DBVR属于集成电路（IC）的线性+开关稳压器。由德州仪器制造生产的TPS76201DBVR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。

description

The TPS76201 low-dropout (LDO) voltage

regulator features an adjustable output voltage as

low as 0.7 V. It is an ideal regulator for sub 1.2-V

DSP core voltage supplies and is equally suited

for similar applications with other low-voltage

processors and controllers. SOT-23 packaging

and the high-efficiency that results from the

regulator’s ultralow power operation make the

TPS76201 especially useful in handheld and

portable battery applications. This regulator

features low dropout voltages and ultralow

quiescent current compared to conventional LDO

regulators. Offered in a 5-terminal small outline integrated-circuit SOT-23 package, the TPS76201 is ideal for

micropower operations and where board space is at a premium.

A combination of new circuit design and process innovation has enabled the usual PNP pass transistor to be

replaced by a PMOS pass element. Since the PMOS pass element is a voltage-driven device, the quiescent

current is ultralow (30 μA maximum) and is stable over the entire range of output load current (10 μA to 100 mA).

Intended for use in portable systems such as laptops and cellular phones, the ultralow-power operation results

in a significant increase in the system battery operating life.

The TPS76201 also features a logic-enabled sleep mode to shut down the regulator, reducing quiescent current

to 1 μA typical at TJ = 25°C. The TPS76201 is offered in an adjustable version (programmable over the range

of 0.7 V to 5.5 V).
