LD39130S300 mA very low quiescent current Linear regulator IC with automatic Green mode | PMIC | 5 | Active | The LD39130S is a high accuracy voltage regulator that provides 300 mA maximum current from an input voltage ranging from 1.4 V to 5.5 V, with a typical dropout voltage of 300 mV.
It is available in DFN6 1.2 x 1.3 mm package and in ultra-small Flip-chip 4 bumps package, allowing the maximum space saving.
The device is stabilized with a ceramic capacitor on the output. The ultra low drop voltage, low quiescent current and low noise features make it suitable for low power battery-operated applications. It integrates an internal logic circuitry, which allows the regulator to be in ultra low consumption mode (green mode), when the output current required is very low. The normal working mode, with fast transient response, is restored when the load current increases.
The enable logic control function puts the LD39130S in shutdown mode allowing a total current consumption lower than 0.1 μA. The current foldback and thermal protection are provided. |

LD392002 A high PSRR ultra low drop linear regulator with reverse current protection | PMIC | 1 | Active | The LD39200 provides 2 A of maximum current with an input voltage range from 1.25 V to 6.0 V, and a typical dropout voltage of 130 mV.
It is stable with ceramic capacitors on the output (10 µF).
Typical power supply rejection ratio is 70 dB at 1 kHz and starts to roll off at 20 kHz.
The enable logic control function puts the LD39200 in shutdown mode, reducing the total current consumption to 10 nA (typ.).
Power Good flag is available on a dedicated pin.
The device also includes reverse current protection, short-circuit constant current limit and thermal protection.
Typical applications are for Telecom infrastructure and consumer. |

LD3985Ultra low drop-low noise BiCMOS voltage regulators low ESR capacitors compatible | Power Management (PMIC) | 5 | Active | The LD3985 provides up to 150 mA, from 2.5 V to 6 V input voltage. The ultra low drop voltage, low quiescent current and low noise make it suitable for low power applications and in battery-powered systems. Regulator ground current increases slightly in dropout only, prolonging the battery life. Power supply rejection is better than 60 dB at low frequencies and rolls off at 10 kHz. High power supply rejection is maintained down to low input voltage levels common to battery operated circuits. Shutdown logic control function is available, this means that when the device is used as local regulator, it is possible to put a part of the board in standby, decreasing the total power consumption. The LD3985 is designed to work with low ESR ceramic capacitors. Typical applications are in mobile phones and similar battery-powered wireless systems. |
