RN5RF series are CMOS-based LDO regulators with external power transistor. By using an external PNP transistor, a low dropout voltage regulator ranging from several tens of mA to several hundreds mA can be configured.
The RN5RF Series are CMOS-based Low Dropout (LDO) regulators designed to be used with an external PNP transistor. This configuration allows the creation of a regulator ranging from several tens of mA to several hundreds of mA current capacity. The series supports input voltages up to 10V and offers fixed output voltage options between 1.2V and 6.0V.
| Supply Current (Iss) | Typ. 30uA |
|---|---|
| Standby Current (Istanapy) | Typ. 0.1uA |
| Dropout Voltage (Voir) | Typ. 0.1V |
| Ripple Rejection (RR) | Typ. 60dB |
| Current Limit (Fold-back Protection) | Typ. 8mA |
| Package Type | SOT-23-5 |
The series requires an external PNP transistor with a low saturation type and hfe of approximately 100 to 300.
The typical ripple rejection is 60dB when f=1kHz and Vout >= 1.6V.
The typical application recommends using Tantalum capacitors of 10uF for C1 and C2.
