Power management integrated circuit (PMIC) is the heart of most modern mobile devices. By utilizing efficient, low-power architectures designed to support a wide variety of functions, PMICs enable longer battery life and reduced cost of ownership. The LM4050QCEM3-2.5/NOPB is a precision voltage reference circuit, which is part of Texas Instruments’ PMIC portfolio. Specifically, the LM4050QCEM3-2.5/NOPB belongs to the Voltage Reference product category.

The LM4050QCEM3-2.5/NOPB is a low-power precision shunt voltage reference with very low offset and temperature drift. It requires only a single external resistor to set the output voltage, and can operate from a single supply or dual supplies. It features very low input bias current, low power operation, and accurate temperature tracking. It is designed for use in a wide range of low-power applications, including voltage source stabilization, overvoltage protection circuits, precision regulation, and thermocouple measurements.

The LM4050QCEM3-2.5/NOPB operates over a wide input voltage range of 2.25V to 14V. Its low offset (<15μV), low temperature coefficient (<7.5ppm/°C), and low supply current (<2.7mA) make it suitable for precise voltage reference applications. It is available in a small 8-bump chip-scale package (CSP) with a 0.88mm pitch and 0.44mm height. This package size makes it well suited for use in portable and handheld electronic products.

The LM4050QCEM3-2.5/NOPB is based on an advanced low-power bipolar technology. Its low supply current (<2.7mA) ensures operation at maximum delivering power of 11mW at an ambient temperature of 25°C. To further reduce power consumption, it features an auto-shutdown mode. This mode can be triggered when the output voltage falls below 1.4V for longer than 60 ms or reaches 1.7V for longer than 1 ms.

The LM4050QCEM3-2.5/NOPB features a high-precision output voltage of 2.5V with a tolerance of ±0.05% over line and temperature. The device can withstand up to 30V transient load without affecting the output accuracy. It also offers excellent temperature stability, with a low temperature coefficient of 7.5ppm/°C and low noise of 33μVrms. Additionally, it is immune to variations in line voltage and power supply transients that may occur in portable electronic products.

The LM4050QCEM3-2.5/NOPB is an advanced precision voltage reference circuit designed for a wide range of low-power and low-footprint applications. Its low offset and temperature coefficient, along with excellent temperature stability, enable precise voltage regulation even in extreme environmental conditions. The chip-scale package also makes it well suited for use in portable and handheld devices.
