Note: Absolute maximum ratings are those values beyond which damage to the device may occur.Functional operation under these condition is not implied. 11ħ LD1117A adjustable: application note. Only chip trimming allows the regulator toreach a very tight output voltage tolerance, within 2 % at 25 C. Only a veryĬommon 10 F minimum capacitor is needed forstability. High efficiency isĪssured by NPN pass transistor. Surface mount packages optimizethe thermal characteristics even offering arelevant space saving effect. The device is supplied in: SOT-223, DPAKand TO-220.
Concerning fixed versions, are offered thefollowing output voltages: 1.2 V, 1.8 V, 2.5 V and3.3 V. (at 25 C) Temperature range: 0 C to 125 CĭescriptionThe LD1117Axx is a low drop voltage regulatorable to provide up to 1 A of output current,available even in adjustable version (V REF = 1.25V). Temperature range High supply voltage rejection:Ĩ0 dB typ.
