General Description
The TX6211C 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 TX6211C series is ideal for today’s cutting edge phone. Internally the TX6211C includes a reference voltage source, error amplifiers, driver transistors,
current limiters and phase compensators.
The TX6211C’s current limiters' feedback circuit also operates as a short protect for the output current limiter and. the output pin. The output voltage is set by current trimming. Voltages are selectable in 100mV steps within a range of 0.9V to 5.0V.
The TX6211C 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.
