1.5 AMP POSITIVE VOLTAGE REGULATOR TEL:805-498-2111 FAX:805-498-3804 WEB:http://www.semtech.com October 3, 2000 DESCRIPTION The EZ1086 series of high performance positive voltage regulators are designed for use in applications requiring low dropout performance at full rated current. Additionally, the EZ1086 series provides excellent regulation over variations in line, load and temperature. Outstanding features include low dropout performance at rated current, fast transient response, internal current limiting and thermal shutdown protection of the output device. A variety of options are available for maximum flexibility: the EZ1086C has both fixed and adjustable voltage options and is designed for use in commercial applications; the EZ1086BC is adjustable only for cost sensitive commercial applications; the EZ1086I is adjustable only for industrial applications. All devices are available in the popular TO-220 and TO-263 packages. APPLICATIONS •= Post regulators •= Battery chargers U1 3 + C1 10uF FEATURES •= Low dropout voltage: 1.3V max. for EZ1086C, 1.4V max. for EZ1086I, 1.45V max. for EZ1086BC •= Full current rating over line and temperature •= Fast transient response •= ±2% total output regulation over line, load and •= •= •= •= •= •= temperature (±2.4% for EZ1086BC) Adjust pin current max 90µA over temperature Fixed/adjustable output voltage (EZ1086C) Line regulation typically 0.015% Load regulation typically 0.05% Industrial temperature range (EZ1086I) TO-220 and TO-263 packages ORDERING INFORMATION (1)(2) DEVICE EZ1086BCM.TR EZ1086CM-X.X.TR EZ1086IM.TR TO-263(3) EZ1086BCT EZ1086CT-X.X EZ1086IT TO-220(4) EZ1086-3.3 IN OUT/TAB GND PACKAGE Notes: (1) Where X.X denotes voltage options (EZ1086C only).

Transient response can be improved by adding a small bypass capacitor from the adjust pin to ground. GROUND This pin is the bottom end of the internal resistor feedback chain for fixed output voltage parts, and should be connected to ground. 2 OUTPUT 3 INPUT This is the power output of the device, and is electrically connected to the TAB. This is the input supply pin for both the control circuitry and the pass device. 4 © 2000 SEMTECH CORP. 652 MITCHELL ROAD NEWBURY PARK CA 91320 1.5 AMP POSITIVE VOLTAGE REGULATOR EZ1086BC, EZ1086C & EZ1086I October 3, 2000 DEVICE OUTLINE - TO-220 DEVICE OUTLINE - TO-263 ECN00-1352 5 © 2000 SEMTECH CORP. 652 MITCHELL ROAD NEWBURY PARK CA 91320
