H7210
The H7210 series are highly accurate, low noise, CMOS LDO Voltage Regulators. Offering low output noise, high ripple rejection ratio, low dropout and very fast turn-on times, the H7210 series is ideal for today’s cutting edge mobile phone. Internally the H7210 includes a reference voltage source, error amplifiers, driver transistors, current limiters and phase compensators.
The output voltage is set by current trimming. Voltages are selectable in 100mV steps within a range of 1.2V to 5.0V.
When the CE input pin is low, the fast discharge channel can pass，a built-in pull-down resistor pulls the output voltage low. Fast discharge function optional.
The H7210 series is also fully compatible with low ESR ceramic capacitors, reducing cost and improving output stability. This high level of output stability is maintained even during frequent load fluctuations, due to the excellent transient response performance and high PSRR achieved across a broad range of frequencies. The CE function allows the output of regulator to be turned off, resulting in greatly reduced power consumption.
H75XX-1
The H75XX-1 series is a set of three-terminal low power high voltage regulators implemented in CMOS technology. They allow input voltages as high as 18V. They are available with several fixed output voltages ranging from 2.1V to 5.0V. CMOS technology ensures low voltage drop and low quiescent current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain variable voltages and currents.
