HT7850 HT7850-A 的詳細介紹
盛群新推出TinyPowerTM低電壓差電源穩(wěn)壓IC HT7850 HT7850-AHT7850 HT7850-A繼廣獲好評的HT71XX、HT73XX、HT75XX系列之后，盛群半導(dǎo)體進一步推出更高輸出電流的低壓差穩(wěn)壓器(Low Dropout Regulator -- LDO) HT72XX及HT78XXHT7850 HT7850-A。主要特色是僅5微安的極低靜態(tài)電流及低輸出入電壓差(Vdrop)，因此可有效延長電池壽命。此外，它也擁有高輸入電壓及高輸出電壓準確性的卓越性能。由于結(jié)合低靜態(tài)電流及低輸出入電壓差的特點，使得HT72XX及HT78XX成為多顆電池應(yīng)用的最佳解決方案。內(nèi)建的保護功能有過電流及過熱保護，為系統(tǒng)及IC提供必要的保護。
利用CMOS技術(shù)制造的低壓差穩(wěn)壓器 HT72XX及HT78XX，可分別提供高達300及500毫安電流，固定輸出電壓支持1.8V到5V的寬廣范圍。因其超低功耗的優(yōu)點，該組件特別適用于相機、手機及手提游戲機等使用電池之低功率產(chǎn)品。

General Description
The HT7850 HT7850-A series of positive, linearregulators features low quiescent current (5mA typ.) with low dropout voltage, making themideal for battery applications. The devices are capable ofsupplying 500mA of output current continuously.
They are available with several fixed outputvoltages ranging from 1.8V to 5.0V. Although designed primarily asfixed voltage regulators, these devices can be used with externalcomponents to obtain variable voltages and currents.
These rugged devices have Thermal Shutdownand Current Limiting to prevent device failure under the "Worst" ofoperating conditions.
The HT78XX Features
The HT78XX Output voltage ranges: Fixed range of 1.8V, 2.5V, 2.7V, 3.0V,3.3V, 5.0V type.
The HT78XX Highly accuracy: ±2%
The HT78XX Low voltage drop: 360mV (typ.), VOUT=5.0V at 500mA
The HT78XX Guaranteed output current: 500mA
The HT78XX Low quiescent current: 5mA (typ.)
The HT78XX Current limiting
The HT78XX Over-temperature shutdown
The HT78XX SOT-89, TO-92 Packages
