Description

The ADP2300 /ADP2301are compact, constant-frequency, current-mode, step-down dc-to-dc regulators with integrated power MOSFET. The ADP2300 / ADP2301 devices run from any input voltage from 3.0 V up to 20 V, making them suitable for a wide range of applications. A precise, low voltage internal reference makes these devices ideal for generating a regulated output voltage as low as 0.8 V, with ±2% accuracy, for up to 1.2 A load current.There are two frequency options: the ADP2300 runs at 700 kHz and the ADP2301 runs at 1.4 MHz. These options allow users to make decisions based on the trade-off between efficiency and the size of the total solution. Current-mode control provides fast and stable line and load transient performance. Each ADP2300 / ADP2301 device includes an internal soft start to prevent inrush current at power up. Other key safety features include short-circuit protection, thermal shutdown (TSD) and input undervoltage lockout (UVLO). Precision enable pin threshold voltage allows ADP2300 / ADP2301 to be easily sequenced from other input/output supplies, or the enable pin can be used as a programmable UVLO input by using resistive divider.The ADP2300 / ADP2301 are available in a 6-lead TSOT package and are rated for the −40°C to +125°C junction temperature range.APPLICATIONSLDO replacement for digital load applicationsIntermediate power rail conversionCommunications and networkingIndustrial and instrumentationHealthcare and MedicalConsumer
