The TL4051B12IDBZR is a micro-power, high-precision CMOS voltage reference that belongs to the category of a PMIC – Voltage Reference. It is characterized by its wide input voltage range, precision voltage output and low quiescent current. Its series resistors are temperature-stable and long-term stable. Depending on the application, different output voltages can be achieved as the TL4051B12IDBZR has three different output voltages (1.2 V, 1.5 V, 2.5 V).

The TL4051B12IDBZR is suitable for many applications where a precision voltage reference is needed. The most common application fields are low-power, precision Buck-Boost converters, current feedback amplifiers, 16-bit ADCs, DACs and temperature sensors. It is also used in micro controllers, power supplies and digital power converters.

The TL4051B12IDBZR consists of a band-gap reference, a temperature compensation circuit and a CMOS circuit with a built-in buffer stage. The band-gap reference voltage generated with an on-chip transistor generates a fixed reference voltage that is temperature independent and stable over time. This reference voltage is amplified and buffered by the CMOS circuit and then compared to the output voltage of the temperature compensation circuit. The result of the comparison forms the control input for the on-chip transistor, which works as a current source and regulates the output voltage.

The main features of the TL4051B12IDBZR are:
Tank Voltage Range: 2.7 V - 5.25 V
Reference Voltage Accuracy: ±1.2 mV
Ripple Rejection: 60 dB
Input Bias Current: 0.6 μA
Quiescent Current: 0.1 μA

The TL4051B12IDBZR is designed to generate an accurate and precise voltage reference suitable for use in low-power applications. Its low quiescent current and temperature-stable resistors make it an ideal choice for precision voltage reference applications.

Overall, the TL4051B12IDBZR is a highly accurate, low-power and micro-power voltage reference suitable for precision voltage reference applications. It features a wide input voltage range, precision voltage output and low quiescent current, making it ideal for many applications including Buck-Boost converters, current feedback amplifiers, 16-bit ADCs, DACs and temperature sensors.
