AN7708集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

AN7708屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由松下電器制造生產(chǎn)的AN7708穩(wěn)壓器 - 線性線性穩(wěn)壓器用于提供穩(wěn)定的輸出電壓，無論負(fù)載電流、輸入電壓或環(huán)境因素如何變化，這些輸出電壓通常都要保持不變。它們的工作原理要求輸入電壓維持在高于所需的輸出電壓，而且要超出某個最小量，并且在工作時會將輸入端的任何多余電壓轉(zhuǎn)換為熱量。對于大多數(shù)應(yīng)用而言，雖然這種穩(wěn)壓器的效率低于開關(guān)模式的穩(wěn)壓器，但它們通常更適合對噪聲高度敏感的應(yīng)用。

■Overview

The AN7700, AN7700F, and AN7700SP series are stabilized constant-voltage power supplies with small difference between I/O voltages (0.5 V typ.). They are suitable for low-voltage, battery-driven equipment, and home

appliances and industrial equipment with great fluctuation of the supply voltage.

The output voltage ranges:

For AN7700, AN7700F

3 V, 4 V, 5 V, 6 V, 7 V, 8 V, 9 V, 10 V, 12 V, 15 V, 18 V, 20 V, and 24 V

For AN7700SP

3.3 V, 3.5 V, 5 V, 6 V, 7 V, 8 V, 9 V, 10 V, 12 V, and 15 V

■Features

?Minimum I/O voltage difference: 0.5 V (typ.)

?On-chip overcurrent limiter

?On-chip thermal protection circuit

?On-chip inrush current protection circuit at the time of input voltage start-up

?On-chip input short-circuit protection circuit (When the input pin is short-circuited to the ground, the

circuit between pins 1 and 3 is shut down to prevent current flow.)

■Applications

?Power supply equipment
