The LN1154B502MR-G is a Linear Voltage Regulators (LDO) ROHS manufactured by National Semiconductor, and packaged in a SOT-23-5L form factor. It is a low dropout (LDO) regulator, specifically providing a regulated output voltage of 5.0V and a 2.0A output current. The device is symmetrical/balanced, meaning that the input voltage range is from 2.3V to 10V, and the maximum junction temperature is +150°C. It features low dropout voltage, low quiescent current, fast dynamic response, line and load transient protection, its maximum quiescent current is 150uA, and it has an enable pin. In summary, the LN1154B502MR-G is a low voltage LDO Regulator ROHS manufactured by National Semiconductor, and packaged in a SOT-23-5L form factor. It offers a 5.0V output voltage, a 2.0A output current, a wide voltage range from 2.3V to 10V, and fast dynamic response.
