DESCRIPTION
The TPS71202 low-dropout (LDO) voltage regulator
is tailored to noise-sensitive and RF applications. It
features dual 250-mA LDOs with ultra-low noise, high
power-supply rejection ratio (PSRR), and fast
transient and start-up response. Each regulator
output is stable with low-cost 2.2-mF ceramic output
capacitors and features very low dropout voltages
(125 mV typical at 250 mA). The regulator achieves
fast start-up times (approximately 60 ms with a
0.001-mF bypass capacitor) while consuming very low
quiescent current (300 mA typical with both outputs
enabled). When the device is placed in standby
mode, the supply current is reduced to less than
0.3 mA typical. The regulator exhibits approximately
32 mVrms of output voltage noise with V_OUT = 2.8 V
and a 0.01-mF noise reduction (NR) capacitor.
Applications with analog components that are
noise-sensitive, such as portable RF electronics,
benefit from high PSRR, low noise, and fast line and
load transient features. The TPS71202 is offered in a
thin 3-mm × 3-mm SON package and is fully
specified from –55°C to 125°C (T_J).
