S-802/812 Series HM Features Low power consumption VOLTAGE REGULATOR The S-802/812 Series are three-terminal voltage regulators that use a CMOS process. The output voltage is fixed internally: the S-802 Series outputs negative voltage, and the S-812 Series outputs positive voltage. Since the S-802/812 Series consume less current and need a smaller input/output voltage difference than existing three-terminal voitage regulators, battery-powered portable equipment can have a higher capacitance and a longer service life. HB Appiications Constant voltage power Smail input/output voltage difference supply of battery-powered (S-81250HG: 30 mV typ. Ioyr = 1 mA) equipment, communications Low temperature coefficient of output voltage equipment, video equipment (S-81230AG: + 0.375 mV C typ.) and others Wide operating voltage range (S-81250HG: 12 V max.)

MB 4123443 0002530 164S-802/812 Series Hi Technical Terms 1. Output voltage (Vout) Output voltage Vout is that voltage guaranteed by the voltage regulator (accuracy + 5%) under given input voltage, output current, and temperature conditions. Changes in these conditions will result in an output voltage that may exceed specification limits. For details, please refer to electrical characteristics and characteristics data. Line regulation (AVout/AVin X Vout) This value represents the degree of dependence of the output voltage on the input voltage. It shows the change in output voltage for a given change in input voltage, with output current fixed. Load regulation (AVourt) This value represents the degree of dependence of the output voltage on the output current. It quantifies the change in output voltage for a given change in output current, with input voltage fixed. Input/output voltage difference (Vgir) Inputting a product's output voltage (Vout) + input/output voltage difference (Vgir) to Vin causes output of Vout x 95%. A low Vgip value suggests that a regulator is (1) capable of delivering constant output voltages even with marginal (low) input voltages, and (2) capable of outputting substantial current. For these reasons, a low Vgjp value is desirable. Note: Vgit is highly dependent on lout .

The error amplifier compares a reference voltage Vref with a part of the output voltage fed back by the feedback resistors Ra and Rg. It supplies the control transistor with the base current, needed to keep a stable output voltage range not influenced by input voltage or temperature fluctuation. 2 Internal circuit 2.1 2.2 Reference voltage circuit In a voltage regulator, the reference voltage circuit plays a very important role because any abnormality wiil show up directly at an output.
