LX8819

LX8819 TM ® Dual Channel 1A Low Dropout Regulator D ATA S HEET DESCRIPTION KEY FEATURES ƒ Two Independent Regulated Outputs ƒ Accurate Output Voltages ƒ Typical Dropout of 1.25V at 1A and 1.1V at 500mA ƒ Independent Thermal and Current Limit Protection ƒ Low Profile 5 Lead SMT Power Package ƒ Low Tolerance Load Regulation ƒ Wide DC Supply Voltage of 3.5V to 10V ƒ Loop Stability Independent of Output Capacitor Type APPLICATIONS The LX8819 is a dual channel positive-voltage linear regulator. This dual regulator has one fixed output coupled with an adjustable output. Each channel features a low dropout and a high accuracy. The LX8819 provides designers with a flexible power management www.DataSheet4U.com solution, minimal printed circuit board area, and shorter design cycles. Each channel can supply up to one amp independently with a regulator design optimized for system efficiency by consuming minimal ground current while directing quiescent current to the load. The LX8819 features on-chip trimming of the internal voltage reference enabling precise output Voltages (typically ±1% of its specified value) while the Bipolar output transistor has a low dropout voltage even at full output current (VDO < 1.25V typical @ 1A). Thermal and Short Circuit Current Protection are integrated on-chip and operate independently for each of the regulator output. The LX8819 regulator is stable with a low-value output capacitor (typically 2.2µF on the outputs) allowing the designers flexibilit...
