The S-8435/8436 Series consists of a reference voltage source, CR oscillation circuit, power MOS FET, diode, and comparator. The output voltage is fixed internally, with an optional shutdown function to minimize current consumption. These regulators are suitable for portable devices due to their small 5-pin package and few external parts requirements.
The S-8435 Series forms a step-up regulator using only an external coil and capacitor, while the S-8436 Series employs an external transistor to boost available output current. Key features include low voltage operation (0.9 V min), built-in CR oscillation circuit, high-precision output voltage, and availability in an SOT-89-5 package.
The regulator supports low voltage operation starting from a minimum of 0.9 V.
The S-8436 Series employs an external transistor to boost the available output current.
The typical current consumption during operation is 5.0 µA.
