| AN6535 4-pin Negative Adjustable Voltage Regulator s Overview The AN6535 is a monolithic 4-pin negative adjustable voltage regulator. With an external resistor, it provides any stabilized output voltages between -5V and-30V, and is optimum for the power circuits with a current capacitance of up to 0.5A. With various protective circuits built in, it has high reliability and is provided in a 4-lead SIL plastic package. 9.6 - 0.1 o 3.1 4.0 + 0.5 Unit:mm 12.5max. 0.70.2 9.0min. 3-1.0 1.8 2.0 0.50.1 1.5 1.3 s Features * Wide range of output voltages:VO= -5 to -30V * Interal thermal overload protection * Interal short-circuit protection * Output transistor safe area compensation 2.3 2.3 2.3 3.3max. 4-pin SIL Plastic Package with Fin (SSIP004-P-0000) s Block Diagram Start Circuit Ref.
