The TPS723-Q1 low-dropout (LDO) negative voltage regulator offers an ideal combination of features to support low noise analog and mixed-signal applications. The TPS723 supports input voltages from –10V to –2.7V, and outputs from –10V to –1.186V (in adjustable configuration). This regulator is stable with small, low-cost ceramic capacitors (up-to 2.2µF), and includes enable (EN) and noise reduction (NR) functions.

The TPS723-Q1 supports very tight DC accuracy of ±1.6% (new chip) over line, load and temperature range. The device responds quickly to line and load transients. The TPS723-Q1 supports a low dropout of typically 140mV (typical, new chip) at 200mA of load current. The device has built-in protection mechanism for over-current and overtemperature for reliable operation of the LDO.

The TPS723-Q1 supports low noise on output (60µVRMS with NR cap of 10nF) and available in a small 5-pin SOT-23 package, with performance fully specified over a temperature range of –40°C to +125°C.

參考設計

PMP30473 — 最低雜訊輔助雙輸出電源供應參考設計

此參考設計為 2 x 1-W 反相降壓升壓轉換器。兩個輸出電壓（+5V 和 -5V）由單一降壓矽 (TPS57160-Q1) 產生。後置穩壓器（和後置濾波器）可確保無漣波輸出電壓。輸入電壓範圍涵蓋汽車與工業應用。

TIDA-00431 — 採用 8 GHz DC 耦合差動放大器的射頻取樣 4 GSPS ADC 參考設計

寬頻射頻 (RF) 接收器可大幅提高無線電設計的靈活性。寬廣的瞬時頻寬允許在不更換硬體的情況下進行靈活調諧，並能夠擷取頻率相差很大的多個通道。

此參考設計說明了一種寬頻 RF 接收器，它採用 4GSPS 類比數位轉換器 (ADC)，並具有 8GHz DC 耦合全差動放大器前端。放大器前端提供訊號增益，並允許擷取低至 DC 的訊號。這是使用平衡不平衡轉換器耦合輸入時無法實現的。
