LD1985 LINEAR INTEGRATED CIRCUIT
VERY LOW DROP AND LOW NOISE VOLTAGE REGULATOR LOW ESR CAP. COMPATIBLE, WITH INHIBIT FUNCTION
DESCRIPTION
The UTC LD1985 is a 150mA fixed output voltage regulator. The ultra low drop voltage and the low quiescent current make them particularly suitable for low noise, low power applications, and in battery powered systems. In sleep mode quiescent current is less than 1μA when INHIBIT pin is pulled low. Shutdown Logic Control Function is available on pin 3 (TTL compatible). This means that when the device is used as local regulator, it is possible to put a part of the board in standby, decreasing the total power consumption.
An external capacitor, CBYP=10nF, connected between bypass pin and GND reduce the noise to 30μVrms.
Typical application is in cellular phone, palmtop laptop computer, personal digital assistant (PDA), personal stereo, camcorder and camera.
FEATURES
LD1985 線性集成電路
非常低壓降和低噪聲電壓穩壓器低 ESR 電容。兼容，帶抑制功能
描述
UTC LD1985 是一款 150mA 固定輸出電壓調節器。超低壓降和低靜態電流使其特別適用於低噪聲、低功耗應用和電池供電系統。在睡眠模式下，當 INHIBIT 引腳拉低時，靜態電流小於 1μA。關斷邏輯控制功能在引腳 3 上可用（TTL 兼容）。這意味著當該器件用作本地穩壓器時，可以將電路板的一部分置於待機狀態，從而降低總功耗。
一個外部電容 CBYP=10nF，連接在旁路引腳和 GND 之間，將噪聲降低到 30μVrms。
典型應用是蜂窩電話、掌上型膝上型電腦、個人數字助理 (PDA)、個人音響、攝像機和照相機。
