SBVS447 January 2024 TPS7A20L
PRODUCTION DATA
Any internal noise at the TPS7A20L reference voltage is reduced by a first-order, low-pass RC filter before being passed to the output buffer stage. The low-pass RC filter has a –3-dB cutoff frequency of approximately 0.1 Hz.
During start-up, the filter resistor is bypassed to reduce output rise time; the filter begins normal operation after the output voltage reaches the correct value.
