PMIC - Voltage Regulators - LinearThe REG102GA-2.8 is a linear voltage regulator designed for use in different application fields, such as in air conditioning controllers, metering systems, and vending machines. It is a monolithic IC with low power consumption, wide operating voltage range and low temperature coefficient.Working PrincipleThe REG102GA-2.8 utilizes a feedback system to convert the input voltage to a stable output voltage. It works in two steps: the first step is to regulate the input voltage by comparing the output voltage and desired voltage through an error amplifier. The output of the error amplifier is then used as the control voltage in the second step, which is a voltage regulator. The voltage regulator, in combination with the resistor divider, can regulate the output of the voltage regulator to the desired voltage, such as 2.8V.FeaturesThe REG102GA-2.8 offers an excellent line and load transient response, with 20mV ripple rejection (at 33kHz), and 0.01%/V control voltage accuracy. This accuracy means that the output voltage can be stabilized under an awkward and large load current. Furthermore, it has the ability to regulate up to 500mA and with an input/output differential of only 0.5V by using external transistors.This voltage regulator also offers a wide operating voltage range from 1.8V to 18V, and its reverse leakage current is low, with a maximum of 10μA—so it is ideal for applications that require low power consumption. Along with low voltage drop, it has a wide operating ambient temperature range (-40℃～125℃).ApplicationsThe REG102GA-2.8 is ideal for cost-sensitive applications such as air conditioning control systems, digital metering systems, solar or wind power applications, and vending machines. It also can be used in powering embedded processors, such as ARM, or digital system management chipsets, as well as low-voltage DC motors and batteries.ConclusionThe REG102GA-2.8 is an excellent voltage regulator for various applications, with a wide operating voltage range, low power consumption, low voltage drop, and excellent accuracy and line and load transient response. It is suitable for cost-sensitive applications and can be used in air conditioning control systems, metering systems, solar or wind power applications, and vending machines.
