7 / 12 page 7 LT1460S3 (SOT-23) APPLICATIONS INFORMATION Longer Battery Life Series references have a large advantage over older shunt style references. Shunt references require a resistor from the power supply to operate. This resistor must be chosen to supply the maximum current that can ever be demanded by the circuit being regulated. When the circuit being controlled is not operating at this maximum current, the shunt reference must always sink this current, result- ing in high dissipation and short battery life. The LT1460S3 series references do not require a current setting resistor and can operate with any supply voltage from VOUT + 0.9V to 20V. When the circuitry being regu- lated does not demand current, the LT1460S3s reduce their dissipation and battery life is extended. If the refer- ences are not delivering load current, they dissipate only several mW, yet the same connection can deliver 20mA of load current when demanded. Capacitive Loads The LT1460S3 family of references are designed to be stable with a large range of capacitive loads. With no TYPICAL PERFORMANCE CHARACTERISTICS Characteristic curves are similar for most LT1460S3s. Curves from the LT1460S3-2.5 and the LT1460-10 represent the extremes of the voltage options. Characteristic curves for other output voltages fall between these curves, and can be estimated based on their voltage output. 10V Output Noise 0.1Hz to 10Hz TIME (2 SEC/DIV) 1460S3 G22 capacitive load, these references are ideal for fast settling or applications where PC board space is a premium. The test circuit shown in Figure 1 is used to measure the response time and stability of various load currents and load capacitors. This circuit is set for the 2.5V option. For other voltage options, the input voltage must be scaled up and the output voltage generator offset voltage must be adjusted. The 1V step from 2.5V to 1.5V produces a current step of 10mA or 1mA for RL = 100Ω or RL = 1k. Figure 2 shows the response of the reference to these 1mA and 10mA load steps with no load capacitance, and Figure 3 shows a 1mA and 10mA load step with a 0.1 µF output capacitor. Figure 4 shows the response to a 1mA load step with CL = 1µF and 4.7µF. LT1460S3-2.5 RL VOUT VGEN 1460S3 F01 CIN 0.1 µF 2.5V 1.5V CL VIN = 2.5V Figure 1.
