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 23μA and 5mA and so is ideally suited to low power and battery

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. OBSOLETE
