A Product Line of Diodes Incorporated ZRC400 PRECISION 4.096 VOLT LOW KNEE CURRENT VOLTAGE REFERENCE Description Pin Assignments The ZRC400 uses a bandgap circuit design to achieve a SOT23 Package Suffix - F precision micropower voltage reference of 4.096 volts. The device is available in a small outline surface mount package, ideal for applications where space saving is important, as well as packages for through hole requirements. The ZRC400 design provides a stable voltage without an external capacitor and is stable with capacitive loads. The ZRC400 is recommended for operation between 23 A and 5mA and so is ideally suited to low power and battery (Top View) powered applications. Pin 1 floating or connected to pin 1 Excellent performance is maintained to an absolute maximum of 25mA, however the rugged design and 20 volt E-Line, 3 pin Package Suffix - A processing allows the reference to withstand transient effects and currents up to 200mA. Superior switching capability allows the device to reach stable operating conditions in only a few microseconds.
