Description : Precision Micropower Shunt Voltage References

Description
The LM4041 is a bandgap circuit designed to achieve a Precision micro-power Voltage reference of 1.225 V. The device is available in the small outline SOT23 and SC70-5 surface mount packages which are ideal for applications where space saving is important.
Both packages are available to 0.5% C grade and 1% D grade for Precision applications. Excellent performance is maintained over the 60µA to 12mA operating current range with a typical temperature coefficient of only 20ppm/°C. The device has been designed to be highly tolerant of capacitive loads so maintaining excellent stability.
This device offers a pin for pin compatible alternative to the LM4041 Voltage reference in both adjustable and 1.225V output variants.

Features
• Small packages:       SOT23, SC70-5
• No output capacitor required
• Output Voltage tolerance

Part Name(s) : MAX6520 MAX6520EUR-T
MaximIC
Maxim Integrated
Description : 50ppm/°C, SOT23, 3-Terminal, 1.2V Voltage Reference

General Description
The MAX6520 is the lowest-power 1.2V, Precision, three-terminal Voltage reference offered in a SOT23-3 package. Ideal for 3V battery-powered equipment where power conservation is critical, the MAX6520 is a low-power alternative to existing two-terminal Shunt References. Unlike two-terminal References that throw away battery current and require an external series resistor, the MAX6520 has a 70µA maximum supply current (typically only 50µA) that is independent of the input Voltage. This feature translates to maximum efficiency at all battery Voltages.

Features
♦ 3-Pin SOT23 Package
♦ 50ppm/°C max Tempco
♦ Supply Current Independent of Input Voltage Over Temperature
♦ 50µA Supply Current
♦ 2.4V to 11V Input Voltage Range
♦ ±1% Initial Accuracy
