LT1764AEQ-3.3#PBF is Analog Devices’ fixed 3.3 V, 3 A LT1764A low-dropout regulator in a 5-lead DD Pak. The LT1764A datasheet specifies 340 mV typical dropout at 3 A, 0.66 V maximum dropout over the full temperature range, 40 µVRMS output noise from 10 Hz to 100 kHz, and 1 mA quiescent current. It is stable with a 10 µF output capacitor and includes current limiting, thermal limiting, reverse-battery protection and reverse-current protection.
The E-grade device is specified for a -40°C to +125°C junction-temperature range, and the #PBF ordering suffix denotes the lead-free model. ZZX Electronics lists 50 pcs with date code 1144. Before replacement or new assembly, verify input headroom, load-transient and thermal requirements, output-capacitor selection, package marking, lot traceability and current Analog Devices lifecycle information. Send an RFQ for lot evidence, inspection options and delivery confirmation.
