Technical content

The AN6541 is a 3-pin 9V voltage regulator which per- forms stable operations up to the minimum input/output voltage difference 0.3V (typ.). Stabilized fixed output volt- age is obtained from unstable DC input voltage. The AN6541 can be used in power circuits with current capacitance up to 300mA. n Features

• Low drop-out voltage:0.3V (typ.)
• Internal short-circuit current protection
• Low temperature coefficient of output voltage AN6541 3-pin Positive V oltage Regulator n Block Diagram Unit:mm 10.4–0.5 1.4–0.1 2.9–0.1 ø3.7 10.5–0.5 2.54 0.45 1:Input 2:Common 3:Output JEDEC:TO –220AB (HSIP003-P-0000) 2.5–0.25 +0.1 – 0.05 123 4.5–0.3 0.8–0.2 Pass Tr R 2 R 1 Q 1 Error Amp.
