RS7300
600mA Adjustable & Fixed Voltage LDO Linear Regulator
Page No. : 1/11
General Description
The RS7300 series is a low‐dropout linear regulator that operates in the input voltage range from +2.4V to +7.0V and
delivers 600mA output current.
The RS7300 is available in two types, fixed output voltage type and adjustable output voltage type. The fixed output
voltage type is preset at an internally trimmed voltage 1.8V, 2.5V, or 3.3V. Other options 1.0V, 1.2V, 1.5V, 1.8V, 2.0V,
2.85V, 3.0V, 3.3V, 3.6V and 5.0V are available by special order only. The output voltage range of the adjustable type is from
1.25V to 5V.
The RS7300 (ADJ type) consists of a 1.25V bandgap reference, an error amplifier, and a P‐channel pass transistor. Other
features include short‐circuit protection and thermal shutdown protection.
The RS7300 (Fixed type) consists of a 0.95V bandgap reference, an error amplifier, and a P‐channel pass transistor. Other
features include short‐circuit protection and thermal shutdown protection. The RS7300 series devices are available in SOT‐
223, SOT‐89 and SOT‐23 packages.
