300mA Low-Noise LDO Regulators
General Description
G924
Features
Low, 90µA No-Load Supply Current
The G924 is a low supply current, low dropout linear
regulator that comes in a space saving SOT-23-5
package. The supply current at no-load is 90µA. In the
shutdown mode, the maximum supply current is less
than 1µA. Operating voltage range of the G924 is from
2.5V to 5.5V. The over-current protection limit is set at
550mA typical and 400mA minimum. An over-tem-
perature protection circuit is built-in in the G924 to
prevent thermal overload. These power saving
features make the G924 ideal for use in the battery-
powered applications such as notebook computers,
cellular phones, and PDA’s.
