General Description

The BDxxKA5 series are low-saturation regulators that are available for output currents up to 500mA. The output voltage precision is ± 1. These LDO regulators are offered in several output voltages and package lineups with or without ON/OFF switches (that set the circuit current to 0μA at shutdown). This series can be used for a broad spectrum of applications ranging from TVs and car audio systems to HDDs, PCs, and DVDs. There regulators have a built-in overcurrent protection circuit that prevents the destruction of the IC, due to output short circuits and a thermal shutdown circuit.

Features

■ Output voltage precision: ±1

■ Low-saturation voltage with PMOS output: 0.12V Typ.(Io=200mA)

■ Built-in over-current protection circuit

■ Built-in thermal shutdown circuit

■ Shutdown switch (BDxxKA5WFP and BDxxKA5WF series)

■ Ceramic capacitor compatible (recommended capacitance: 1μF or greater)

Applications

Microcontrollers and all electronic devices that use logic circuit

BD33KA5WF屬于集成電路（IC） > 線性 + 開關(guān)穩(wěn)壓器。羅姆半導(dǎo)體集團(tuán)制造生產(chǎn)的BD33KA5WF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。
