www.analog.comtime stability than even the best bandgap references. Unique circuit design makes the LT1021 the first IC reference to offer ultralow drift without the use of high power on-chip heaters. The LT1021-7 uses no resistive divider to set output voltage, and therefore exhibits the best long term stability and temperature hysteresis. The LT1021-5 and ...
LOW DROPOUT LINEAR REGULATOR - Diodes Incorporated
www.diodes.comIts circuit includes a trimmed bandgap reference to assure output voltage accuracy to be within ±1%. On-chip thermal shutdown provides protection against a combination of high current and ambient temperature that would create excessive junction temperature. The AZ1117C is available in 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5.0V fixed ...

It is important for reference stability that VREF is bypassed to GROUND with a ceramic capacitor connected as close to the pin as possible. A minimum value of 0.1-µF ceramic is required. Additional VREF
